1 year ago I showed you guys the super
thin rackmount gaming systems that I was planning to build for my kids then a few
months ago I showed you guys the V2 that solved a lot of the problems with the
initial prototype but ended up introducing some of its own today it
reaches its final form and I have some really cool stuff to show you guys
including these awesome PCIe risers from Cay custom PCB designs this lowprofile
EK water cooling that makes the whole thing so slim and solution for powering
them on and off that actually works this time I hope seriously this latest
version of the design is so cool I think some of you might want to follow along
from home check this out the GPU to deal with the signaling issues with our
Optical DisplayPort goes in the front now that's
awesome like this awesome Segway to our sponsor build Redux many people find
building a PC to be a real hassle and to build Redux well that just ain't right
so they want to do the heavy Lifting for you with vast configuration options and
competitive pricing versus building a PC yourself kick your feet up relax and
check out build Redux at the link below the frustrating thing about our last
design is how close it was to being game
ready everything fit in the oneu and we
even showed it working at the end of the video with great temperatures I might
add but it had an Achilles heel this I'm
not even saying the quality is bad they might have been great but we needed
these to get from where the GP U was located in the front of the case to
where it needs to plug in in the back and every time you add a connection you
add some loss this combined with the fact that we're using active Optical
DisplayPort cables in the walls meant that the monitors just weren't lighting
up reliably under normal circumstances the solution would be simple why don't
you just put the GPU in the back exactly where it's supposed to go but because
this is a oneu Slimline chassis that would really limit the types of gpus
that we could installing it not to mention interfere with plugging anything
into the PCIe expansion slots that are now all blocked as for what else has
changed the answer is pretty much everything starting with the motherboard
we went with a prime b650 M A2 from ASUS
and the main reason that we chose it aside from that it fits in our slim oneu
profile without needing modifications to the io like we've had to do in the past
is that it's a CSM board which is short for corporate stable model these
motherboards might not be marketed for gaming but they're every bit is capable
and they enjoy an extended product support life cycle as well as not
wasting any money on things like RGB lights so they're quite affordable each
of these is about 140 bucks
then for CPU we've gone with the ryzen 57600 X look I'm not going to argue that
this entire project isn't completely off the rails like five oneu gaming systems
liquid cooled by a pool but for the individual systems themselves I didn't
want to go way over kill I mean my kids are using these things thanks so this is
a mixture of bang for the buck performance today with six high-speed
Zen 4 cores and a platform that I can expect to get long-term upgrades at
least for a generation maybe two cooling
is where things get really interesting though see under normal circumstances
you'd have a CPU water Block Plus fittings plus a tubing Bend radius that
makes the whole assembly about this High that's not an option if you want to
build a one new system so EK has these
amazing am5 oneu specific blocks this is
the WB am5 rack nickel plus Inox which
basically means it's a nickel plated base it's rack friendly using these G18
style fittings and it has a stainless steel top little tip I haven't talked
about before is if you're ever not sure if youve put enough thermal compound on
there's a super quick and easy way to check just Mount the cooler which with
an LTT screwdriver shouldn't take take you very long then just pop it off and
check as long as you've got full or near complete coverage of the integrated heat
spreader you're good to go there was an old myth that if you reapplied it there
would be bubbles underneath it or something like that but that is simply
not true the mounting pressure is way too high for that boy has it ever gotten
easier choosing system memory these days a year ago even 6 months ago there were
these huge trade-offs for price to Performance but now this 32 gig kit of
ddr5 6 cl30 was under $100 it's like
sheesh so it's pretty much just a matter of picking something that will work
optimally with your platform in our case AMD so we do want low latency DDR 6000
then something that will physically fit
so your case and your cooler don't interfere with them one of the downsides
of a CSM board is that it's not going to have high-end features like 10 gig
networking but as you can see we left an extra slot in our IO in oisk of all
people makes a 10 gig network card that goes in an m.2 slot all you got to do is
plug it in run this little extendo cable
and then put this wherever you want we're using the same in-win cases as
before with the NVMe back plane stripped out of them but we've made a couple of
small modifications the io Shield obviously has to be our custom 3D
printed one courtesy of Antoine from the lab we've added 3D printed brackets for
power supply mounting yeah nice and these screaming
fans have been replaced by adorable little 40 mm noct toas because we're not
really cooling that much with them just what RAM chipset vrms the major heat
generating components the CPU and GPU all that's going to be pulled out by the
water I've gotten ahead of myself a little bit here though to keep the system low
profile this case uses these super tiny
motherboard standoffs that need to be hand installed before you you can
actually put the board in man Antoine outdid himself with all these 3D printed
brackets and accessories and stuff that is solid for the power supply these
power supplies are super cool 850 watts in this tiny form factor and
what's really wild is they're not even that loud boom just goes in like that
awesome I'm doing the most important and fun job ever which is prepping the whips
as I'm calling it that are going to come off of the manifold and the rack and
connect our computers to the water cooling system it's just we have to make
12 of them now and well lus can make the
other ones in the future I think fitting on one side quick disconnect on the
other pops into the back of the computer I heard that you know they always do
this yeah that's fine they finish it just enough to shoot the conclusion of the video and then leave me to finish it
on my weekend mhm exactly what I need is
to get water into this system and for that that we are going to use a PCI
bracket pass through magig what we do is we take both sides we put these G14
adapter fittings in them little something like that then we Mount this
right here and boom we can run tubes to
the inside we can run tubes to the outside can you install all of those
yeah I dropped my pencil yeah that's fine also that is a pen so no it's not
it's a mechanical pencil all right oh you just got
corrected something I can do while she works on that you're done hey yeah uh oh
good I need to put in my SSD these are so overkilled Jake uh yeah so I asked
Micron for some temporary ssds and they were like well you know if we're going
to send them to you it' be cool if they were Gen 5 and I was like okay these are
4 terab 700s yes it's 4 terabytes we
were telling the people these are reasonable systems it's a placeholder
we're going to net boot them later I guess this is going in here now but it
definitely doesn't match the theme of the rest of the build our gpus for
example I bought used on eBay for reasons that I will explain a little bit
later SSD is probably worth more than my GPU I sort of forgot how these worked
you have to take this whole thing apart let me show you how this works a PCI
slot doesn't uhoh I see it oh oh wow
seriously that little post like that oh my goodness uh just use your mag okay or
use your tiny little fingers okay or use your magnet use your magnet on your
whatever without screwing anything up we put this post back in here we get
this o-ring back in here so it doesn't leak all over the inside of the computer
there we go just like that and then you can see what happens is it takes these
round openings and then it converts them
into these slit openings that will fit in a PCI bracket that's how we can use
these as a pass through neat huh I don't know yeah fair enough you'll think it's
neat when you're playing Minecraft on this see unlike the last time we built a
computer for you as a video you actually get to use this one and keep
it I still I kept the case in case she ever wants it again when she like I
don't know you never know but uh I don't like pink anymore oh why did you put it
on your screwdriver then yeah as much can I put in the screws please
absolutely I'm just going to put them in the right spot for you and then you can
screw them in which bit is it it's the
one yeah that's right make sure you got the ratchet set the right way yeah there
you go good job how come the bits aren't all
the same and the shapes all the same on the screws that is a really good
question sometimes it has to do with the cost slot ones for example are really
cheap to manufacture so that's why they use those sometimes it has to do with
the different parts of the world that you might be in some types are more
common in certain parts of the world and other types are more common in other parts of the world sometimes it has to
do with we just didn't realize realized that there was a better way of doing it
so there's older standards and newer standards and sometimes a really big one
for example just doesn't fit on a really small part so you need different sizes
yeah but why can't they just be all the same shape yeah I mean you're not wrong
I realiz I never mentioned what case we're using this is an inwin RS 110 but
you probably wouldn't recognize it because we stripped out all of the drive
cages and the NVMe back plane normally you'd be able to put 10 NVMe drives in
the front of it but now it's going be a GPU and honestly this piece is just for
Aesthetics uh this doesn't hold anything oh but what it does do is here we go
clip into the other piece ah there we go
so it should hold really nicely at the front what's that for this is so that
you can use the computer way over there in the gaming room but the computer
itself with all the noise and all the heat can sit in the server room cool and
we don't get to see any of the indicator LEDs nope nope all right so this is the
computer instead of the laptop yes you're not going to have to use the
laptops anymore they're perfectly powerful for the games that these guys
play but I don't know what it is about laptops and just not wanting to be used
as a desktop they constantly stop working with the external Monitor and
they turn on their own internal display even though I tell them not to they constantly go to sleep even though I
told them don't do that even when you're closed it's just been kind of a pain in
the butt these are kind of a fun choice for our gpus we went with RTX 3080s it's
it's a last gen GPU that is a great deal on eBay right now and is still great in
terms of performance but the specific ones we chose are xc3 from EVGA and it
just felt like this is going to be my last chance to build an EVGA powered
gaming system I might as well take advantage of it also because it's a last
gen card the blocks for these kind of on
clearance right now so we were able to get a good deal on our water blocks
mountains yeah yes Mountains for our fittings we've gone with kind of an
unusual Choice 1/4 in barbs for the GPU
and the reasons for that are twofold one
in such a space constrained system it's a lot easier to deal with thinner tubing
and number two remember how I showed you guys the
G18 threading on the CPU blocks you
can't really get G18 fittings to/ in barbs because that wouldn't make any
sense so we're stuck with the small diameter tubing anyway wa no way these
are PCIe Gen 5 yeah they're designed for
Gen 5 that is sick I mean this is only a Gen 4 card so it doesn't really matter
but these are from uh C pane custom PCB
designs and basically it's exactly what it sounds like it's a custom PCB design
on the card side we've got a device adapter this plugs in here there's six
pin PCIe power for the power that comes
into the bottom of the board then these these are mcio connectors this is like
the New Gen 5 hotness for PCI extension
then on the other side he's got this one new compatible slim SAS LP Riser that he
built for another client he happened to have some pcbs kicking around which
worked out great for us and finally we've got these slim SAS LP to MCI
cables that will theoretically give us PCIe Gen 4 even at oh wow that's really
long this kind of distance quick PSA here you might not have encountered PCIe
signal strength issues if you've never run a riser but like any signal you can
run into a myriad of problems the further that signal needs to travel back
in the PCI gen 3 days the spec included extra signal power to account for the
use of risers meaning that you could rest pretty easy even if you were using
one that headro does not exist with PCI Gen 4 and Gen 5 meaning we're entirely
at the mercy of the motherboard manufacture to leave enough extra signal
at the slot so the added loss from a riser still works with the GPU in our
our case we're limiting the amount of extra signal loss by using highquality
adapters and cabling as our Riser but we're also using a less expensive
motherboard which despite its smaller size helping the situation a bit uses
lower quality components like through hole soldered instead of surface mount
PCIe slots which can incur more loss than you'd see on a higher-end board
with better components at worst we'll have to manually set the PCI slot to gen
3 speeds in the bias which isn't a huge deal given the use case but it's
important to keep in mind that if you have to use a riser with newer components to plan according you can get
around some of the signal limitations by adding a retim that boosts the PCIe
signal but if the 300 post long level one text Forum thread is anything to go
by your mileage may vary so when possible it's best to just not use a
riser we just don't have that luxury here before we plug it in though we need
to get our GPU mounted and this is kind of cool you can see this piece at the
front here I just put the peel back on here because I realized otherwise it's going to get mangled basically it slips
in on the bottom side and then these are
3D printed out of uh what did you say it's 3D TPU yeah it's mushy okay I think
I got it let's do a test can you pull
this out don't try that hard okay good that's good enough okay
it's in as long as it doesn't get pushed in by just you know inserting a display
port cable then we're good now we can go ahead and run our connectors okay these
look very fragile do you think you can handle this yeah okay all right I don't
have backups so hey good job I I believed in you I
completely believed in you it was Jake who didn't believe in you Jake like this
to Jake Jake's sad now my system is
progressing super fast now thanks to my big helper good job I'm not that big no
but you're a big help while she works on getting the tubing tightened by the way
we're using this awesome stuff from Ek that it would probably last longer than
the freaking system what is this for like fuel lines you see how it says
Gates on there yeah that's an automotive brand so okay something that I need to
change on the CPU block is that we don't really have room to have the inlet and
the outlet come in this side so I've got to pull off these stop fittings and put
them on the other side okay so I'm going to put this on and then you're going to
worm drive this on for me okay darling you just got to hold it with your left hand there you go while you screwed them
with your right hand good job one of the other changes I haven't mentioned yet is
the power supplies that we're using to go from 12vt to the 24v that these iicon
dogs take these ended up being a little bit big for the new configuration so
we've gone with these super compact ones from thly some company on Amazon sure
some company on Amazon thanks Jake all we had to do was take these handy dandy
little splicer migs that they come with
and then just put whatever leads we wanted on them so we've got SATA power
to one side and then we've got the barrel Jack that goes into the back of the icon in terms of putting this on I
guess velcro that's what we've been doing all right did we have to go to
like a small small shop to get these extensions or something uh we got them
from MX today oh from Memory Express you're going to plug this end in like
this well you're going to try wait uh-oh
has anyone actually tried these yet these are 8 Pin EPS to PCI adors what no
they're not there's no way no it says
extension but it doesn't have the Gap it does we got it does oh wait what what
the heck it's right on this one or right on that part of that one the top left is
square oh the the holes are wrong I'm talking about like where the cables go
where the cables go is right okay so as
long as we just mash it in there then we're good is it yeah yeah it is right
okay so we just need an exacto knife I'll grab one so all we've got to do is
take this little guide right here that is part of the PCIe connector but not
part of the a pin EPS connector shave it
off try not to slice open our finger no
cut towards yourself it's the rule I know you're right the point is do as I
say not as I do don't cut towards yourself then this should go in there
like that hey all right no problem well
small problem this is not really locked in place anymore for some reason oh wow
these are awful well thanks mimx all I need to do now is get power to my fans
which is just going to go a little something like that power to my PCIe
device adapter okay that's uh in really good
there and then I guess I actually do need to put the fans in I really hope I
accounted for the space I need for these and they just kind of clip in like what
the bottom Clips in first like that wait
these are backwards there's your problem yeah do they go on this side backwards
how this is backwards oh no are you
kidding me oh no this is in backwards
line is Sebastian are you kidding me okay this is a minor problem Oh Flip
Flip theing yeah I the fans around that might be less work that's less work
absolutely less work yeah the tubing the tubing classic lonus moment I could have
sworn I looked at the other one before I did yeah not very closely swear a yeah
all right these are coming out what do you think David is this going to just go
and everything's going to be fine yeah I still don't understand how these go in
other side the other side oh cuz they go on that still trying to put them in the
other side it's not perfect m not by a
long shot hey hey all right enough enough
come on come on but it's in I just have
to run this USB cable to the back of the iicon dock ah little something like that
sure uh that seems fine then it runs all
the way over here to the other side and then out the back like this you know
what we are going to leave a lot of that inside oh wow um
yeah we're going to find a spot for that later and then this ah runs to one of
the USB 3 ports my system is just about done all I need is the fiber module for
the back of the iicon dock but mine is actually uh keeping a fiber optic cable
safe over in the server room so I will wait until I take it over there
everything looks good there's no water in it right now so we're just going to turn it on until we see something and
then stop there's no pump to run dry because the pump and the radiator are
both external so we're not worried about that either okay she's on she's off well
this one's not happy oh good we're off to a great start let's try another one I
blame the child who helped me typical
typical adult let's try the original system cuz
we know that that one works wait wait roll roll remember the
polarity matters on the power switches on these
cases oh yeah is it
yep here we go here we go here we go is
my power on on the other side oh my God are you kidding me yeah what way does it
go I forgot about that I forgot about that so Brown towards the
io completely forgot about that I was ready to lose another half an hour of my
life to that brown towards the eye oh so what you unplugged it and then just like
clicked it with a piece of metal and it worked that is the dumbest thing I've
ever heard yeah it's a server case thing of some sort I don't know okay post shut
it off heck shut it off it's not even warm at
all it's fine let's get the GPU tested then okay oh that's funny so it was
pressing the power button and then holding it I get it that's why it wasn't turning on ha very funny it just posted
with the GPU in does it detect the GPU
wow the CPU is at 85° you know what would actually help
better where's that water bowl I'm just going to put some water on it move your hand move your hand this is a really
strange idea evaporative cooling this is the peak idea we had here
put water on the computer is there any way to get water into it if you have a
piece of tube in a funnel I do not take responsibility for this Jake decided you
know what it doesn't need it update the BIOS while it didn't have any water
running through it okay so we're we're manually this is basically the
equivalent of computer CPR we're we're manually circulating the heart right now
the block is much cooler than before I think this is actually this is not the
stupidest thing have done today it's pretty high up there
though it did finish yeah it's rebooting
updating the RGB BIOS now BIOS is updating LED firmware yep can confirm
great put your finger in the Stream is it warm probably prob feels nice oh yeah
that's definitely warm it's about the temperature of
P okay what is that is that wet oh yeah that's wet okay off off off off off off
for really hopefully it's around and not on
the board do you want to blow in the other side put all those microbes in
there brother it's like a Renaissance pain um awesome it doesn't do you see it
in there at all it's hard to tell from here these got to come off come off
first everything everything's got to come off okay I'm heading
out I see an O-ring you know what actually the way that this design is
designed I don't think any water got on the
GPU there is a little in there but there's a big space between the back of
the you see there's a big gap there that
being said the reason that this happened these EK Pro terminal kits that give you
the 45° angle uh they're usually squared
off we had to shave these down to make them fit on these blocks and I think
this one didn't get shaved quite enough
so that it wouldn't properly clamp lamp down on that side so if I file this a
bit more and then tighten it back up it should be fine we fixed our GPU leak we
needed to add the O-rings at the terminal uh whoopsie on that one I
installed the drivers it's detected but does it
work W nice keep putting water in there
should we game or CPU temperature
reports as 45° that's not bad call it it's it's also only 22 Watts so that's
actually not that great Colin go faster if you wait if you squeeze it
harder does it does it go down yeah it does we're
down to 40 39 come
on 38 how much water you got left you
got enough for a whole game a battle bit wow I haven't played this yet but it
seems like this would be a lot of fun I died but it works let's check our attempts see if Colin's been doing a
good job 51° on the CPU I imagine this is not a very hard to run game uh what
about our GPU 42° oh got him oh got him
got them just like you're going to get this segue to our sponsor rocket money
