00:00:00.240 --> 00:00:07.600
after months of trials and tribulations the next gen desk pc has finally gone

00:00:05.279 --> 00:00:12.719
from render to reality now our ambitious goal of

00:00:10.080 --> 00:00:17.600
creating a water-cooled pc and a desk that's no thicker than a regular desk

00:00:15.599 --> 00:00:24.560
all without compromising on either gaming performance or silent operation

00:00:21.359 --> 00:00:26.480
has not been easy but by the time we're

00:00:24.560 --> 00:00:28.960
done this video you guys are gonna see it all laid out

00:00:28.080 --> 00:00:33.920
and operational and i'm a layout for you the

00:00:31.439 --> 00:00:38.160
benefits of our sponsor ridge wallet ridge wallet wants to redefine the

00:00:35.680 --> 00:00:41.920
wallet with its compact frame and rfid blocking plates check out how they can

00:00:40.079 --> 00:00:47.760
keep your wallet bulge down and use offer code lioness to save 10

00:00:44.079 --> 00:00:47.760
and get free worldwide shipping

00:00:55.840 --> 00:01:01.760
why don't we kick it off with what went well using the model we marked our

00:00:59.920 --> 00:01:05.680
three-quarter inch sheet of birch wood then used a table saw to break it into

00:01:04.000 --> 00:01:09.600
all the components we needed to build the box that you're looking at the only

00:01:07.760 --> 00:01:13.119
slightly tricky part was creating a little lip here on the side rails so

00:01:11.439 --> 00:01:17.439
that the glass top will have a place to sit so once we've finalized the

00:01:15.280 --> 00:01:21.680
component placement it's as simple as throwing the bottom piece here onto the

00:01:19.200 --> 00:01:25.439
router and going and cutting all the holes that we're

00:01:22.960 --> 00:01:30.240
going to need for final assembly but

00:01:27.600 --> 00:01:32.640
what about uh what about this why don't you run me through

00:01:31.759 --> 00:01:37.280
this well these are our rez's or attempts at

00:01:35.040 --> 00:01:41.759
them anyway it's gonna look great whenever i can get it to work we tried

00:01:40.240 --> 00:01:47.439
so many different ways so here's the thing clear materials like

00:01:45.119 --> 00:01:53.840
acrylic they're not forgiving like wood or aluminum one wrong move can cause it

00:01:50.399 --> 00:01:55.280
to crack or even shatter and because

00:01:53.840 --> 00:02:00.240
it's clear you can see the damage from literally

00:01:58.079 --> 00:02:04.479
every angle yeah a lot of my experience is with metals

00:02:02.320 --> 00:02:08.959
which are much more forgiving to work with on my shop laser i just couldn't

00:02:06.479 --> 00:02:13.440
get the cut right uh i couldn't get the settings to not light itself on fire and

00:02:12.319 --> 00:02:18.080
it's something that i could have probably dialed in but

00:02:15.440 --> 00:02:21.840
i decided to move on from v1 here vaporized acrylic likes to get a little

00:02:19.920 --> 00:02:27.520
burny and given the 10 watt per millimeter rule of thumb 130 watts of

00:02:25.040 --> 00:02:32.080
power for 18 millimeters of acrylic is pushing the limit a little so for the

00:02:29.760 --> 00:02:37.120
second go-around our pals over at metalmart gave it their best with their

00:02:34.239 --> 00:02:42.959
water jet and initially we had high hopes but the brittleness of the acrylic

00:02:39.920 --> 00:02:46.000
reared its ugly head again causing just

00:02:42.959 --> 00:02:47.120
these beautiful cuts around the LTT

00:02:46.000 --> 00:02:51.920
but unsightly craters everywhere where the

00:02:49.840 --> 00:02:56.400
water jet pierced the stock in an attempt to make the holes so i pivoted

00:02:54.239 --> 00:03:00.080
from that to the router something i was really trying to avoid because these

00:02:58.160 --> 00:03:05.519
parts are really well suited for 2d fabrication and it went surprisingly

00:03:02.400 --> 00:03:07.840
well but i failed to brass off or dull

00:03:05.519 --> 00:03:13.440
the tip of the drill and it pulled out a huge chunk of material and scrapped this

00:03:09.840 --> 00:03:15.280
attempt as well so close yet so far

00:03:13.440 --> 00:03:20.400
thankfully though while we were busy with techtimber trotec sent over this

00:03:18.560 --> 00:03:25.599
beauty right here and it was time to give it another shot

00:03:23.200 --> 00:03:30.799
because while the raw power of this unit is actually about the same as columns

00:03:27.599 --> 00:03:34.000
laser at 130 watts as the name suggests

00:03:30.799 --> 00:03:36.640
the speedy 400 flex runs circles around

00:03:34.000 --> 00:03:41.280
prosumer tools moving literally 10 times faster which we can use to our advantage

00:03:39.120 --> 00:03:47.519
now in the router version of the part these slots all around it were designed

00:03:44.480 --> 00:03:49.840
to increase volume and improve water

00:03:47.519 --> 00:03:55.599
flow but the thing is partial cuts like this aren't something

00:03:51.920 --> 00:03:58.640
that a laser can typically do you see an

00:03:55.599 --> 00:04:00.799
etch pass only removes a fraction of a

00:03:58.640 --> 00:04:06.560
millimeter of material but here's the thing with the speedy i can just run the

00:04:03.840 --> 00:04:12.080
same edge over and over and over and over again and this piece right here

00:04:09.760 --> 00:04:17.519
oh there it is took a couple of hours but if you look the entire surface of

00:04:15.040 --> 00:04:22.320
the LTT is actually a couple of millimeters lower than the outer rim

00:04:20.160 --> 00:04:27.600
that's almost as big brain as buying all your clothes from ltcstore.com

00:04:25.199 --> 00:04:32.479
now small holes in thick material are another thing that's pretty tricky with

00:04:29.520 --> 00:04:38.000
a laser mostly because a laser beam isn't actually cylindrical but rather

00:04:35.360 --> 00:04:42.880
conical and as you can imagine a cone shape is not the ideal shape for a

00:04:40.880 --> 00:04:46.240
threaded hole so instead of drilling all the way through i just made little holes

00:04:44.800 --> 00:04:50.880
and then finished them afterwards on the drill press that way they're on location

00:04:48.320 --> 00:04:56.800
and to the correct size unfortunately after solving this problem it went

00:04:52.560 --> 00:04:57.840
together great and it even held water ah

00:04:56.800 --> 00:05:03.840
that doesn't really sound very unfortunate okay okay i'm getting to that uh in the midst of disassembling it

00:05:02.000 --> 00:05:07.840
i got distracted by the camera falling over and i fat fingered the drill's

00:05:05.520 --> 00:05:13.039
direction lefty loosey became ready tidy and uh i made a little crater oh no

00:05:15.360 --> 00:05:21.600
oh it's otherwise perfect yeah she's dead jim okay but

00:05:19.919 --> 00:05:27.440
even though this is just a cosmetic sample then we are confident now that we

00:05:24.400 --> 00:05:29.280
can build it since i mean you did do it

00:05:27.440 --> 00:05:32.639
once i did what it held water you just had to i was so close

00:05:33.120 --> 00:05:40.160
what it means is we're confident confident confident that we can build it

00:05:38.560 --> 00:05:44.320
which means we're not going to have to resort to some kind of commercial

00:05:42.080 --> 00:05:49.600
off-the-shelf reservoir we know we can rely on having this and we can do the

00:05:46.800 --> 00:05:54.400
final layout for the rest of the parts right yes confident confidence he's

00:05:51.919 --> 00:05:58.000
confident look at this guy these 1u radiators from alphacool are

00:05:56.320 --> 00:06:01.120
super neat they're actually designed for servers but they've got some cool

00:05:59.520 --> 00:06:06.160
features that make them perfect for our use case as well they've got the inlet

00:06:03.039 --> 00:06:08.400
and outlet on either side of the rad and

00:06:06.160 --> 00:06:13.280
then check this out you can chain them together in cereal by using these end

00:06:10.479 --> 00:06:17.199
ports or you can go in and out on this side so what we're going to be doing

00:06:15.680 --> 00:06:21.360
is we're going to be lining the right side of the table

00:06:18.880 --> 00:06:25.360
here we go with these radiators we just made a small oopsie and we only ordered

00:06:23.600 --> 00:06:29.680
one of them as part of our proof of concept so you'll have to imagine that

00:06:27.440 --> 00:06:33.919
there's more of them over here the only question is is that going to be

00:06:31.600 --> 00:06:38.639
enough radiator surface area i think we're going to have about the equivalent

00:06:35.759 --> 00:06:41.600
of a dual 120 millimeter red and with the way that we're positioning the fans

00:06:40.000 --> 00:06:47.360
we'll show you that in a minute it should be enough first beck the idea

00:06:44.639 --> 00:06:52.720
here is massive positive pressure we're gonna have eight Noctua industrial ppc

00:06:50.080 --> 00:06:56.960
fans with filters basically creating this pressurized chamber in the case

00:06:55.039 --> 00:07:00.400
that's gonna cause the air to kind of passively

00:06:58.160 --> 00:07:06.080
whoosh over the components that need air cooling like the motherboard chipset and

00:07:03.280 --> 00:07:09.199
vrms for example and then exhaust through the only part of the table

00:07:07.759 --> 00:07:13.840
that's not sealed which is going to be the radiators so

00:07:11.840 --> 00:07:18.240
like that when it came time to choose a power supply while we did have a lot of

00:07:15.840 --> 00:07:23.039
options most of them were absolutely terrible because you can get 1u power

00:07:21.039 --> 00:07:28.000
supplies i mean even fancy redundant ones but the issue is they're designed

00:07:25.199 --> 00:07:31.520
for servers which are not made to be quiet!

00:07:28.960 --> 00:07:39.360
so we went with one of these this is an 800 watt

00:07:34.639 --> 00:07:41.759
dc atx power supply from hd plex

00:07:39.360 --> 00:07:47.520
super cool product right because we've got enough power for a threadripper and

00:07:44.240 --> 00:07:50.720
rtx 30 series graphics card but

00:07:47.520 --> 00:07:53.199
passively cooled and super slim

00:07:50.720 --> 00:07:56.960
these get used for all kinds of projects from computers to av to i mean pretty

00:07:56.160 --> 00:08:04.000
much any situation where you need a high power dc power supply these guys are

00:08:00.960 --> 00:08:06.240
super cool of course the thing about ac

00:08:04.000 --> 00:08:12.160
the thing about dc power supplies that is ones with a 12 volt input and then

00:08:08.800 --> 00:08:14.639
3.3 5 volt and 12 volt outputs is that

00:08:12.160 --> 00:08:19.039
they still need to do the ac conversion from the wall so for that we're

00:08:16.639 --> 00:08:23.520
employing two of these 400 watt power bricks also from hd plex these puppies

00:08:22.240 --> 00:08:27.280
because they're kind of messy looking and because we

00:08:25.280 --> 00:08:31.919
want them to have access to fresh air we're actually gonna put on the outside

00:08:29.840 --> 00:08:36.399
of the unit on the underside now let's talk motherboard because um

00:08:35.039 --> 00:08:41.839
okay i can't come up with a good reason for this because AMD sent it to me i'm

00:08:38.959 --> 00:08:47.440
using a ryzen 3970x on an ASUS zenith 2 extreme

00:08:45.839 --> 00:08:53.279
is this the alpha or the non-alpha i think it's the alpha it's not alpha

00:08:51.360 --> 00:08:56.800
it's the non-alpha which is fine because realistically we are not going to be

00:08:55.120 --> 00:09:00.320
overclocking this thing anyway we had to make a couple of small modifications to

00:08:58.720 --> 00:09:04.240
the board it was so close to being too thick to

00:09:02.640 --> 00:09:10.160
fit in our case we actually had to remove the cover on the vrm fans here as

00:09:07.360 --> 00:09:14.399
well as the cover on the i o so it'll look a little more

00:09:12.320 --> 00:09:18.320
industrial just like last time we're going to be setting the motherboard and

00:09:15.920 --> 00:09:22.560
the graphics card back probably about an inch or an inch and a half from the edge

00:09:20.480 --> 00:09:27.600
what this allows is because the i o is on the rear this time some room for the

00:09:24.720 --> 00:09:31.279
cables to bend or have large connectors before they just butt right up against

00:09:29.440 --> 00:09:34.720
the wall now you might have noticed if you're extremely keen eyed that this is

00:09:32.959 --> 00:09:38.240
a 3080 that is not the graphics card that we

00:09:36.800 --> 00:09:43.279
actually intend to use for the final project we're gonna go with a 30-70 just

00:09:40.720 --> 00:09:47.200
to keep power consumption under control oh god we're going to need custom cables

00:09:45.360 --> 00:09:52.080
yes uh actually they're silverstone compatible so i can get custom cable mod

00:09:49.760 --> 00:09:55.920
cables perfect so cable mod just yep easy peasy fire that up check the box

00:09:54.240 --> 00:10:00.800
while i may be on the record saying that i think the lang ddc pump is a piece of

00:09:58.800 --> 00:10:05.839
unfortunately in a 1u enclosure we just don't have a

00:10:03.279 --> 00:10:12.080
choice so the next best thing to using a good pump like a d5 is using two ddcs so

00:10:09.360 --> 00:10:14.959
at least if one of them fails you've got another one

00:10:13.200 --> 00:10:19.680
so i'm just putting these here as like a placeholder for now we're gonna have to

00:10:17.600 --> 00:10:24.240
tweak this a little the last piece that i have to show you guys today is our

00:10:22.079 --> 00:10:28.240
water block this is also from alphacool and this thing is super neat so not only

00:10:26.880 --> 00:10:36.560
does it have a large enough cooling plate for our ryzen threadripper processor it has a total of eight

00:10:32.880 --> 00:10:39.360
options for inlet ports and outlets what

00:10:36.560 --> 00:10:45.600
that does is it allows us to put it onto the CPU socket and then

00:10:42.320 --> 00:10:48.079
figure out with our RAM and our vrm

00:10:45.600 --> 00:10:52.399
cooling and all that stuff how the heck we're gonna be able to get tubes in and

00:10:49.839 --> 00:10:57.920
out of it i lied there is actually one more thing we've got four two terabyte

00:10:54.880 --> 00:11:00.480
crucial ssds with the intention being

00:10:57.920 --> 00:11:05.600
kind of to take up space as much as anything else but also that'll give you

00:11:02.560 --> 00:11:07.600
know eight terabytes of i mean who cares

00:11:05.600 --> 00:11:11.839
we could check them in raid zero yes get that performance eight terabytes of

00:11:09.279 --> 00:11:14.800
solid state storage in addition to an m.2 boot drive

00:11:13.680 --> 00:11:21.440
but hear me out i know you want this on the outside i do

00:11:19.200 --> 00:11:25.519
but could we put it here we could but i really don't want to and

00:11:23.519 --> 00:11:29.040
this is just because of the distance that this 12 volt run has to go well

00:11:27.279 --> 00:11:33.279
we're putting a heat source next to the radiators you see like if we have these

00:11:31.200 --> 00:11:37.760
on the outside of the case then all this heat isn't input into the system and

00:11:35.440 --> 00:11:43.040
we're already pretty tight on on air flow in here that's fair so this is i

00:11:40.640 --> 00:11:47.760
mean assuming about 90 efficiency that's like under full load that's like 80

00:11:45.440 --> 00:11:52.160
watts that we can have yeah outside but under your realistic load we're probably

00:11:49.680 --> 00:11:55.279
talking 40 watts but even that do you really think airflow's going to be tight

00:11:53.519 --> 00:11:58.079
we've got eight cooling fans but we have a lot of pressure we don't have a lot of

00:11:56.560 --> 00:12:01.680
flow it just has such a small orifice to come out of i

00:12:00.240 --> 00:12:04.959
think you're going to be surprised probably but i want to plan for less

00:12:03.760 --> 00:12:09.200
heat in the system that's why we went with a 30 70. i wanted a 30 80. but like

00:12:07.519 --> 00:12:13.279
like then where would those go right i mean we could move the red down

00:12:11.600 --> 00:12:16.160
and then like have them here and then they're close to the SATA ports yeah

00:12:14.720 --> 00:12:19.680
we're gonna and we're gonna need tubing runs and stuff like that this area is

00:12:18.240 --> 00:12:23.680
fine we're gonna use those little end connectors that i used for the

00:12:21.920 --> 00:12:27.279
stacking radiators video so these will be tight but what we could do is we

00:12:25.519 --> 00:12:31.600
could go pumps and then we could go drives here actually the outlet port for

00:12:29.519 --> 00:12:34.720
the water block is in here so there's no sense really having a pump out here well

00:12:33.440 --> 00:12:40.880
i couldn't help noticing that our reservoir still isn't actually

00:12:37.680 --> 00:12:43.120
manufactured fine i can change that see

00:12:40.880 --> 00:12:47.120
if i had done my job and made this right then it would be set and i

00:12:45.279 --> 00:12:52.560
wouldn't have to entertain these ideas you like my ideas come on

00:12:50.800 --> 00:12:56.079
okay so let's pull the cables off this for now yeah yeah no it's a mess with

00:12:54.160 --> 00:12:59.120
them this might seem crazy but we're gonna be painting this for the finished

00:12:57.600 --> 00:13:03.920
product anyway so drawing on it is not that stupid

00:13:02.000 --> 00:13:08.880
so here's what i'm thinking right angle here into the end cap here then we go

00:13:07.360 --> 00:13:15.200
straight out of here here we've got a height problem this is

00:13:11.519 --> 00:13:18.160
lower than this we go this way

00:13:15.200 --> 00:13:23.120
and then into here we go out from here into the graphics card out of the

00:13:20.160 --> 00:13:26.959
graphics card and then out from here into reservoir

00:13:25.200 --> 00:13:30.560
very sub-optimal from a filling perspective it will take like an hour or

00:13:29.200 --> 00:13:34.959
two to fill this yeah i was kind of hoping to put ports

00:13:32.320 --> 00:13:37.120
in the actual desk and have a fill and a drain area

00:13:36.240 --> 00:13:42.399
i see that we can also use these because they're

00:13:40.560 --> 00:13:49.279
just vertical so we can put the fill funnel up here and just fill it my god

00:13:45.120 --> 00:13:51.519
you're a genius so we can fill the res

00:13:49.279 --> 00:13:54.959
and flood the pumps so they don't run dry for the filling process yeah

00:13:54.000 --> 00:14:00.800
okay build in the quality of life you want right i did not think of that well you

00:13:58.800 --> 00:14:05.040
did you know what does teamwork make the dream work for

00:14:02.160 --> 00:14:09.040
one okay so can you get me uh my little uh my little valve it's technically not

00:14:07.440 --> 00:14:12.720
the symbol for a valve but it'll allow it oh sorry you're right that's that's

00:14:10.800 --> 00:14:18.079
the incorrect signal symbol for a valve let me fix it

00:14:14.800 --> 00:14:18.079
there fixed it for you

00:14:19.839 --> 00:14:24.639
you know the reference right this

00:14:22.880 --> 00:14:29.040
is sick man this is good it's gonna be fine i think it'll be yeah just not a

00:14:27.440 --> 00:14:32.240
nightmare and whenever you need to look at it oh i'm so glad you used the word

00:14:30.720 --> 00:14:36.880
nightmare because i have one for you oh great we've been having some issues with

00:14:34.160 --> 00:14:39.920
the aquantia nyx and our new switches okay and this is an on-boarder quantum

00:14:39.920 --> 00:14:45.279
there's no way we're fitting a 10 gig card without another riser what if it

00:14:43.440 --> 00:14:49.279
was here well how is that going to fit right

00:14:49.440 --> 00:14:55.120
why why have you done this well Jake found the problem so Jake is

00:14:53.600 --> 00:14:58.560
my issue blame Jake i do but i do need an add-in card

00:14:57.199 --> 00:15:02.639
where's it gonna go well if it was here we would just have

00:15:00.560 --> 00:15:06.720
another cutout there's a lot of cutouts we're gonna have a cut out here here

00:15:04.880 --> 00:15:11.040
here like and this is supporting that huge sheet of glass we could do like a

00:15:09.360 --> 00:15:16.880
couple support pillars little bogeys yeah yeah i'm so excited right now

00:15:15.600 --> 00:15:21.360
now hopefully i won't have to wait eight months for the next part no guarantees

00:15:20.000 --> 00:15:27.519
one thing you never have to wait for though is my segways to our sponsors

with added low end extension and adjusted driver damping for superior

00:15:46.079 --> 00:15:51.120
