WEBVTT 00:00:00.000 --> 00:00:08.760 nine months ago we designed the perfect rack mounted gaming PC it's got it all 00:00:05.640 --> 00:00:11.460 it's a completely custom skinny one you 00:00:08.760 --> 00:00:17.160 chassis it offers Up Maximum performance while using custom water cooling to 00:00:13.920 --> 00:00:19.080 achieve dead silent operation and it 00:00:17.160 --> 00:00:25.619 keeps all the heat out of the room for those hot summer gaming sessions and now 00:00:21.960 --> 00:00:30.060 we're throwing all of it away why 00:00:25.619 --> 00:00:31.920 price it was too darn High especially if 00:00:30.060 --> 00:00:36.840 I want systems for me my wife my kid my other kid and my other kid and this 00:00:34.620 --> 00:00:41.640 isn't just me being a cheapskate dad the quote I got back for the cases was 1700 00:00:40.020 --> 00:00:47.160 each and I'm thinking to myself there's got 00:00:43.860 --> 00:00:49.200 to be a cheaper way a jankier way a 00:00:47.160 --> 00:00:54.420 Linus Tech tips way and ladies and gentlemen 00:00:50.940 --> 00:00:57.379 we found it meet the almost ideal one 00:00:54.420 --> 00:00:57.379 new gaming case 00:00:57.500 --> 00:01:04.739 yeah awesome just like this awesome 00:01:01.260 --> 00:01:06.900 segue to our sponsor covalence set aside 00:01:04.739 --> 00:01:10.560 your unused flash sale discount Dev courses with untethered access to 00:01:08.939 --> 00:01:13.680 covalence's comprehensive web development curriculum you'll learn to 00:01:12.240 --> 00:01:17.360 build websites and applications as efficiently as possible check them out 00:01:15.780 --> 00:01:22.140 using the link below it's toasty yeah it's a big problem all 00:01:20.400 --> 00:01:25.920 the heat generating Electronics in the house are in this room which is 00:01:23.700 --> 00:01:29.340 insulated with not even so much as a window to the outside 00:01:27.600 --> 00:01:33.180 fortunately there's a plan for that that's why these 1u gaming machines are 00:01:31.799 --> 00:01:37.799 designed with those external water cooling fittings because the idea is 00:01:35.640 --> 00:01:43.020 that they're going to be plumbed up to these pipes right here that are going to 00:01:39.600 --> 00:01:45.600 carry all the heat from the CPUs gpus to 00:01:43.020 --> 00:01:50.280 the outside where those lines actually run to the outer walls of my swimming 00:01:47.939 --> 00:01:55.079 pool so all the heat from this room gets dumped into the pool hopefully helping 00:01:52.500 --> 00:02:00.240 save on my gas bill for now we need to do a proof of concept build and 00:01:57.780 --> 00:02:03.960 one of the challenges is that there's already not a ton of space left in my 00:02:02.280 --> 00:02:09.420 rack down here and I really don't want to add a second rack so that's why each 00:02:06.180 --> 00:02:11.940 of these systems is just one rack unit 00:02:09.420 --> 00:02:16.980 deep that means we can do five for the entire land Center in half the space 00:02:14.520 --> 00:02:22.020 that it would take if we did 2u systems which would be a lot easier but 00:02:19.260 --> 00:02:27.900 completely fill up my rack as you can imagine building a gaming PC into such a 00:02:24.540 --> 00:02:30.480 slim profile just 4.4 centimeters is a 00:02:27.900 --> 00:02:36.840 real challenge because everything from the usual power supplies to gpus to even 00:02:34.319 --> 00:02:43.980 things like motherboards will typically exceed that profile so 00:02:40.739 --> 00:02:46.739 what's a slim gaming PC Enthusiast to do 00:02:43.980 --> 00:02:53.099 well for starters we ended up with this really cool motherboard from ASRock rack 00:02:49.739 --> 00:02:57.840 it takes a regular LGA 1700 processor 00:02:53.099 --> 00:03:00.900 it's got four dimm slots PCIe by 16 m.2 00:02:57.840 --> 00:03:04.620 actually dual m.2s for storage onboard 00:03:00.900 --> 00:03:08.840 10 gig networking and all in a really 00:03:04.620 --> 00:03:12.180 weird form factor this is what ITX like 00:03:08.840 --> 00:03:13.800 wide Edition this doesn't have a 24-pin 00:03:12.180 --> 00:03:18.239 power connector we can talk about that later first I 00:03:16.200 --> 00:03:22.680 want to talk about this case rather than custom fabricating something Antoine 00:03:20.459 --> 00:03:26.519 from the Labs team thought I bet we could find something off the shelf that 00:03:24.480 --> 00:03:31.860 could be modified to meet all of our requirements and he came up with this 00:03:28.980 --> 00:03:39.239 which costs just a fraction of the custom solution at two hundred dollars 00:03:35.000 --> 00:03:41.220 well not quite Inman sent us the more 00:03:39.239 --> 00:03:45.080 expensive version of this case that comes with the power supply and it's 00:03:42.780 --> 00:03:51.000 about 700 to 800 uh that's not the budget that I approved 00:03:49.080 --> 00:03:58.459 I mean anyone sent it to us for free yeah but I need four more how much is it 00:03:54.360 --> 00:03:58.459 it's it's it's four hundred dollars 00:03:59.280 --> 00:04:04.379 it's a server man it's for businesses not normal people okay we're not using 00:04:03.180 --> 00:04:09.540 the power supply for the rest of the units then what else have we changed well 00:04:07.440 --> 00:04:12.659 all of these Drive mounts they're gone yeah they have no back plane that 00:04:11.400 --> 00:04:19.380 they're connected to so see you later buddies those are going to be replaced with your fiber optic USB extender these 00:04:16.919 --> 00:04:24.300 are super cool these docks from icon allow you to plug a USB device in from 00:04:21.900 --> 00:04:28.259 functionally anywhere that you can run a fiber optic cable so I guess that just 00:04:26.220 --> 00:04:32.639 goes into the front kind of hereish yeah and we also printed this custom front 00:04:30.180 --> 00:04:36.720 plate for it there's a nice honeycomb pattern the next modification we had to 00:04:34.320 --> 00:04:40.560 do was replace these super noisy server fans so we got these 40 millimeter knock 00:04:38.699 --> 00:04:44.400 to a fence that squeeze right on in there are we worried that that's not 00:04:42.000 --> 00:04:51.000 going to be enough airflow uh no we're not it's that's your problem 00:04:47.580 --> 00:04:52.740 basically cool but these fans have to 00:04:51.000 --> 00:04:57.840 move back from where they are so this has been drilled out yes it's uh just 00:04:55.680 --> 00:05:03.240 press fit in it's a there's literally the case there's no 00:05:01.380 --> 00:05:06.120 screws for it maybe having engineer's isn't as great as I thought this is the 00:05:04.860 --> 00:05:11.040 final version of the stubby by the way knurling is now in place we've got the 00:05:09.060 --> 00:05:14.880 tension of this fixed and this is the final molding for the handle 00:05:12.320 --> 00:05:20.820 lttstore.com this doesn't fit at all nope okay we 3D printed a customer oh no 00:05:18.180 --> 00:05:24.800 way all that sick oh yeah and it's even got a fiber optic 00:05:22.800 --> 00:05:31.259 pass-through for the fiber optic USB thankfully Alpha cool makes these 00:05:27.660 --> 00:05:33.120 awesome low profile CPU water blocks so 00:05:31.259 --> 00:05:37.259 theoretically we shouldn't be giving up basically anything in terms of cooling 00:05:36.000 --> 00:05:41.100 wait how the devil is this supposed to install 00:05:39.539 --> 00:05:46.160 long story short our mounting hardware is missing so we're going to move on 00:05:42.780 --> 00:05:49.440 from that for now RAM 00:05:46.160 --> 00:05:54.000 hey we're using the custom RAM that I 00:05:49.440 --> 00:05:55.500 built at Micron that is almost too tall 00:05:54.000 --> 00:06:01.560 but not quite nice how much is this board 00:05:58.220 --> 00:06:03.660 669 what the heck I guess I have to give 00:06:01.560 --> 00:06:08.880 up on Remote Management and having the memory oriented correctly in favor of 00:06:06.120 --> 00:06:14.880 something much more affordable with only a single 10 gig Network Port thanks to 00:06:11.280 --> 00:06:17.880 this cool little m.2 to 10 gig adapter 00:06:14.880 --> 00:06:19.740 from innodesk all right we're going AMD 00:06:17.880 --> 00:06:22.979 baby so I don't even know what CPUs in there I don't know what CPUs in it 00:06:21.000 --> 00:06:27.300 either did you guys notice that this motherboard is bowed due to the back 00:06:25.319 --> 00:06:33.419 plate here you realize this is becoming a pattern right fit before 00:06:30.080 --> 00:06:36.360 no what a mess yeah don't no what are 00:06:33.419 --> 00:06:41.699 you doing these are all laid out this is your 12 volt to 24 volt converter ah 00:06:39.240 --> 00:06:47.240 this takes power off of our power supply you can see it's modified with a Molex 00:06:43.919 --> 00:06:51.060 connector here and then adapts it to oh 00:06:47.240 --> 00:06:54.479 what used to be the barrel Jack power 00:06:51.060 --> 00:06:57.600 supply for this icon fiber optic USB dog 00:06:54.479 --> 00:06:59.940 thing DC DC conversion is much more 00:06:57.600 --> 00:07:03.419 efficient than going from AC to DC so that's why this thing can be cooled 00:07:01.440 --> 00:07:05.780 passively rather than with a fan we're just gonna 00:07:05.880 --> 00:07:12.900 put it there I am Gravely worried this bracket was 00:07:10.680 --> 00:07:18.259 supposed to go in when we had a smaller motherboard I see 00:07:15.600 --> 00:07:23.759 I mean I am no longer Gravely worried phew What GPU are we using well this is 00:07:21.780 --> 00:07:28.860 still the placeholder one so it's a 30 90. okay I mean that's a little op do 00:07:27.120 --> 00:07:34.139 you have any idea of like What GPU you actually want in these systems eventually used 30 series might actually 00:07:32.280 --> 00:07:38.160 be the way to go right now man I bet I could get cheap water blocks for them 00:07:35.819 --> 00:07:42.180 last gen water blocks always discounted one of your big 00:07:40.500 --> 00:07:45.900 complaints the last time we did this was that the GPU was upside down you want 00:07:44.400 --> 00:07:51.360 the water block to be visible when it's in your rack this is a platform to place 00:07:48.599 --> 00:07:55.919 the GPU on and also run the Riser cable underneath so it can plug in here so 00:07:54.000 --> 00:08:00.660 that it shows up nicely when you open the case hey that's pretty cool my brain 00:07:58.620 --> 00:08:05.039 hurts Antoine from the Labs team just sent us this picture 00:08:02.340 --> 00:08:08.639 of the block and a back plate mounted to another of this board 00:08:07.139 --> 00:08:12.419 the block came with the right mounting hardware but we've decided to move ahead 00:08:10.380 --> 00:08:15.240 with our cheaper board anyway due to cost but we'll still show you some of 00:08:13.860 --> 00:08:21.900 the cool Solutions we came up with for this one let's look you can get right angle adapters 00:08:18.479 --> 00:08:23.520 for your internal USB header cool right 00:08:21.900 --> 00:08:27.660 we actually probably still need that cool we don't need it are you sure 00:08:25.440 --> 00:08:30.319 that's it was a height issue for us yeah should be fine 00:08:32.039 --> 00:08:37.979 I'm getting flashbacks to when you broke my motherboard I did not yeah you did 00:08:35.880 --> 00:08:43.560 the port's all wonky now oh my God Linus did we break the USB 3 00:08:41.399 --> 00:08:48.540 everything's fine you know what this is better I accept your solution where did this 00:08:47.160 --> 00:08:52.800 come from though is this part of the case the brackets part of the case but 00:08:50.820 --> 00:08:55.920 these were sent from alpha cool they're like the old school pass-throughs with 00:08:54.420 --> 00:08:59.940 PCIe slots for when you couldn't fit water cooling in your case wow that is a 00:08:58.200 --> 00:09:04.019 really over engineered solution for that when you can just drill a hole and run a 00:09:02.160 --> 00:09:07.500 tube through it I just got all the front i o hooked up here we were pretty close 00:09:05.640 --> 00:09:11.640 to powering this thing on I think yeah we just need our drives oh or drive yeah 00:09:09.899 --> 00:09:17.880 I only have room for one yeah I wasn't sure which one you wanted if you wanted to go price conscious or just price 00:09:15.600 --> 00:09:22.800 conscious sweet that's a two terabyte sabrin rocket cool that's a very 00:09:20.700 --> 00:09:28.640 affordable Drive these days but still ripping fast where is this supposed to 00:09:25.140 --> 00:09:31.140 go to oh I know this just passes through 00:09:28.640 --> 00:09:36.060 anywhere at the back of our case I guess and then plugs into a USB 3 port on the 00:09:33.720 --> 00:09:41.640 motherboard because this is how we get our USB signal to our 00:09:39.200 --> 00:09:46.080 fiber optic adapter and then you've got DisplayPort right yeah this we actually 00:09:43.980 --> 00:09:50.580 have the proper pass-through for because it's tied to our PCI pass-through 00:09:49.140 --> 00:09:54.540 bracket thing for the water cooling I think nope it's just under it so we got 00:09:52.380 --> 00:09:58.080 this handy dandy right angle connector ooh things are kind of coming together 00:09:57.000 --> 00:10:04.800 here I think we just got to get the tubing runs done okay let's do it so I can just 00:10:02.700 --> 00:10:08.640 plumb this up however I want now yep all right I know guys I said that this was 00:10:06.899 --> 00:10:13.080 going to be the final form the next time I did an update on this thing and 00:10:10.680 --> 00:10:15.680 there's still a fair bit of Jank here but 00:10:16.140 --> 00:10:22.980 what were you expecting this is pretty good for me there is one more thing 00:10:21.180 --> 00:10:28.080 before we can try to actually deploy this will it close 00:10:26.640 --> 00:10:32.220 um yeah oh hey look at that 00:10:30.480 --> 00:10:40.760 wow that is a lot of gaming PC in a very 00:10:35.279 --> 00:10:43.620 very thin enclosure oh why is it wet 00:10:40.760 --> 00:10:49.920 oh is this just dripping out from here no no that's a lot of water uh 00:10:47.040 --> 00:10:55.320 oh oh it's coming from inside I think are these not even quick disconnects 00:10:52.019 --> 00:10:57.600 they're just draining water oh well 00:10:55.320 --> 00:11:01.980 that's good then awesome 00:10:59.700 --> 00:11:06.480 that's actually great news though yeah it's not in the system uh it's under the 00:11:04.980 --> 00:11:10.500 power supply but that could just be coming through 00:11:08.040 --> 00:11:15.240 the bottom power supply is sealed I think it's probably fine I mean okay 00:11:16.740 --> 00:11:19.940 you need to turn this off now 00:11:26.279 --> 00:11:32.519 okay well that's where it was leaking 00:11:29.880 --> 00:11:36.540 I'm just glad it all still runs I don't know if there's any additional 00:11:34.620 --> 00:11:42.019 water I think these collars are doing basically nothing though 00:11:38.940 --> 00:11:42.019 they're just looking pretty 00:11:44.399 --> 00:11:50.940 that's why it leaked then because the tubing was stretched and the collar is 00:11:48.000 --> 00:11:55.079 not actually compressing the outer part of the tube against the inner Barb 00:11:52.980 --> 00:11:58.579 let's just try again I mean what could go wrong 00:12:01.760 --> 00:12:08.579 since we're on our way the goal is to replace this station first this is my 00:12:06.300 --> 00:12:14.279 sun station or as I call it the shrine to how a temporary solution is the most 00:12:11.579 --> 00:12:18.600 permanent solution we've got the egpu equipped laptop we've got the power bar 00:12:16.740 --> 00:12:24.899 down there it all is great got this dongle 00:12:21.720 --> 00:12:27.240 no more all right let's see if our 00:12:24.899 --> 00:12:32.040 DisplayPort pass through Works before we put it in the rack I uh was gonna 00:12:29.820 --> 00:12:37.560 just put it in the rack and hope for the best but it hasn't been that kind of day 00:12:33.839 --> 00:12:39.540 fresh boot attempt here we go 00:12:37.560 --> 00:12:44.279 and it's powered off the issue right now is that the system 00:12:41.820 --> 00:12:48.060 does not stay on it could be anything could be the flex 00:12:46.500 --> 00:12:52.920 of the board from when we screwed it down 00:12:49.860 --> 00:12:55.800 could be the water it could be the PCIe 00:12:52.920 --> 00:13:00.600 extension that could be broken boys I um 00:12:58.560 --> 00:13:03.019 I don't know if this system is powering on today 00:13:03.240 --> 00:13:09.360 you know in a way I think the leak was a blessing in disguise because while the 00:13:07.500 --> 00:13:15.060 system probably doesn't look very different we took the opportunity to use that time 00:13:13.019 --> 00:13:20.820 to clean up a few items that weren't really final form the icron dock at the 00:13:18.660 --> 00:13:26.160 front now for example is screwed into place from the top the GPU is now 00:13:23.700 --> 00:13:30.300 screwed into place using the PCIe Riser so that's not going anywhere we figured 00:13:28.800 --> 00:13:35.040 out the missing shark teeth on these fittings were why they weren't sealing so we added a couple zip ties those 00:13:33.060 --> 00:13:38.459 shouldn't be coming loose we 3D printed an i o shield for the new motherboard 00:13:36.420 --> 00:13:42.420 including proper pass-through for our 10 gig as well as our fiber optic cable and 00:13:40.920 --> 00:13:46.320 replace these Quick Connect fittings at the back with ones that don't lose quite 00:13:43.980 --> 00:13:50.760 as much water when you unplug them all of which means this should work 00:13:48.480 --> 00:13:56.360 perfectly this time with no hiccups whatsoever why would you say that 00:13:53.220 --> 00:13:56.360 oh yeah it's going 00:13:56.600 --> 00:14:03.839 hey there we go it's a ryzen 7 3700x oh 00:14:01.980 --> 00:14:09.800 it's the third gen man it's quiet what is making all the 00:14:06.600 --> 00:14:09.800 noise in here these days anyway 00:14:11.399 --> 00:14:18.139 oh right old old wanek which is not at 00:14:15.779 --> 00:14:21.260 my house let's get into the 00:14:21.839 --> 00:14:29.760 wrap mine and my wife's gaming machines look just downright inefficient okay so 00:14:26.639 --> 00:14:31.800 maybe it's this one to go oh yes 00:14:29.760 --> 00:14:36.240 Adam we forgot a solution to remotely power it on oh no we didn't look at all 00:14:34.079 --> 00:14:41.940 of our wonderful options oh my God oh my God oh wow which one are we using 00:14:39.779 --> 00:14:48.660 um we've got 2.4 gig we've got Wi-Fi we've got a pi KVM oh Pi KVM is super 00:14:46.079 --> 00:14:52.560 cool that sounds like a bigger project for another day though this is probably 00:14:50.279 --> 00:14:57.660 gonna be the easiest for today you just use it like a little car 00:14:54.300 --> 00:14:59.399 starter oh no way yeah this solution 00:14:57.660 --> 00:15:04.920 comes to us courtesy of Silverstone maker of things you never thought you 00:15:02.459 --> 00:15:13.019 needed until the moment you need them it plugs into a USB 2 header for power 00:15:07.920 --> 00:15:17.339 it appears that this is so you can 00:15:13.019 --> 00:15:21.480 Orient it any number of different ways 00:15:17.339 --> 00:15:24.839 depending on your system layout which is 00:15:21.480 --> 00:15:28.139 pretty clever all right and then this 00:15:24.839 --> 00:15:30.060 plugs into the hell my God this is a one 00:15:28.139 --> 00:15:35.699 new system Adam I don't know if this is going to work this board plugs into your reset and 00:15:33.779 --> 00:15:39.540 your power switch and then the ones on the front of your case plug into these 00:15:37.920 --> 00:15:44.940 male extensions that way both the remote starter and the 00:15:42.480 --> 00:15:50.279 original one from the case should work funny thing about usb headers I've never 00:15:47.760 --> 00:15:54.620 done this on purpose but technically nothing would prevent you from bending 00:15:52.139 --> 00:16:00.060 the pins I'm doing a very bad thing right now 00:15:57.480 --> 00:16:05.360 should we try it okay yeah let's try it if it still works oh oh you want to 00:16:01.800 --> 00:16:05.360 power it on let's fob it 00:16:08.040 --> 00:16:15.360 hold on am I about to see something that I have literally never seen before in my 00:16:12.120 --> 00:16:17.899 life okay watch this all I'm gonna do is 00:16:15.360 --> 00:16:23.760 turn it around what and then we get this weird Behavior 00:16:21.060 --> 00:16:28.500 where it powers on right away and then Powers off because I think it's 00:16:26.339 --> 00:16:31.500 being held down if I do it in that orientation 00:16:29.760 --> 00:16:38.160 and then I press it and it does nothing wow I reverse it 00:16:34.980 --> 00:16:40.259 I have never seen this before in all my 00:16:38.160 --> 00:16:45.600 years and it works normally learn something new every day 00:16:42.540 --> 00:16:47.100 now let's see if this Powers it off we 00:16:45.600 --> 00:16:51.600 did it but can it power it on 00:16:49.380 --> 00:16:55.380 ah yes okay let's go 00:16:53.160 --> 00:17:02.240 it occurs to me we haven't tested the range on this 00:16:58.079 --> 00:17:02.240 um Adam you ready yeah ready 00:17:04.679 --> 00:17:10.500 did it turn on nope 00:17:08.339 --> 00:17:15.780 how about from in here it did it yeah it's on oh okay well 00:17:13.260 --> 00:17:22.199 that's not too far almost Moment of Truth time 00:17:18.720 --> 00:17:24.959 all I gotta do is patch the fiber optic 00:17:22.199 --> 00:17:30.000 connection from that USB dock into the fiber optics that are in my walls 00:17:26.939 --> 00:17:33.000 already so just all right there we go 00:17:30.000 --> 00:17:34.799 one of those plug my DisplayPort which 00:17:33.000 --> 00:17:39.120 is already run through a fiber optic cable through the walls 00:17:36.600 --> 00:17:45.419 it detected something but did it detect enough 00:17:41.340 --> 00:17:47.760 this wall plate is still using this big 00:17:45.419 --> 00:17:50.940 style adapter that I had intended to replace 00:17:49.080 --> 00:17:55.080 well at any rate the reason I was opening it up was to try plugging 00:17:52.860 --> 00:17:58.140 directly into the optical cable rather than through a pass-through plate and 00:17:56.460 --> 00:18:03.380 the fact that we have the worst kind of pass-through plate here is well it gives 00:18:01.020 --> 00:18:03.380 me hope 00:18:04.679 --> 00:18:09.900 I think it doesn't like having an extension on the other side I think it 00:18:08.460 --> 00:18:14.480 wants to be plumbed straight into the source so we got to move that GPU over 00:18:17.880 --> 00:18:26.220 I might have done a thing wow wow the kids have a lot of Minecraft 00:18:23.700 --> 00:18:32.120 worlds on here okay fancy stuff to see here why don't we go with that one uh oh 00:18:30.059 --> 00:18:36.539 um no oh no no no no no no no no no no no 00:18:35.220 --> 00:18:40.559 no Squarespace if you're looking at 00:18:38.700 --> 00:18:44.940 creating and sharing your
