I am thinking of finally building a wall PC. This is after I bought Phanteks Evolv ATX Airflow Edition just to realise that no matter the amount of fans it’s still too hot/loud and it can’t fit an extra radiator…
Here is what I am currently thinking:
Here is the sketchup project file if someone wants to move things around.
Anyone have any suggestions relating to layout?
I don’t think I will change the position of the rads without a very good reason. I feel like this is an efficient way to exhaust the hot air without extra fans.
This will be open on all sides with perhaps a perspex sheet in the front at some point. All cables will be routed at the back including MOBO IO.
The components aren’t actually the ones I will use but are about the same size. Reservoir will also have pump integrated at the bottom so it will be about as high as 3 fans.
System Spec (some comps will be added/replaced):
Ryzen 2700X (Now have 6700K)
X470 ATX motherboard (Intel for now)
Vega 56 with EK waterblock (owned)
32GB corsair ram (owned)
2x XSPC Rads (1 owned)
Seasonic Prime 750W PSU (owned)
XSPC Photon 270 Reservoir/Pump Combo V1 (owned)
1x SATA SSD (can be mounted at the back)
1x M.2 NVME drive

dont see the image
Do you have system specs? ( Saw vega 56 but not sure on cpu)
Do you have a budget on the case / mods etc

Forum upload issue, added external link for now. Adding spec to OP now.

Not sure how nice having the gpu on the side like that will be, would consider having it above lower part of mobo, reason being is since its an AM4 system you pretty much need to have the gpu in the first x16 slot or 2nd running at 8x assuming x series board. That ribbon cable running from either slot to the gpu will be pretty ugly.
Might be interesting to have the IO facing the bottom of the wall mount since it will have cables running from it.
I consider direct plugging the GPU but mounting would be ugly since I see no way to mount it without using some metal bracket attached to the back.
PCI at 8x is fine perf wise and long PCI extensions are fine as well.
Do other PCI slots run at below 8x? Will have to look into it bit more.
The first layout was with IO to bottom but it would be messy since I couldn’t route them at the back and have it come out one spot. I will probably use just 1 usb port and a hub in the monitor.
They will run off the Chipset that only has 4 3.0 lanes
If you want to upgrade a bit you could go X399 and then all the 16x slots would run the gpu fine, could go for their lower end cpu and have room to upgrade to more if you needed later. Down side is much more expensive on the mobo side, not crazy more expensive on the cpu side if you go for the low one imo.
A little bised but x399m is only $300 on newegg or $270 after rebate
Do you mean x4 speeds?
Intel, even x399 is a downgrade IMHO. Maybe if I had more money than sense… 
If I needed more than Ryzen I would go with threadripper but I see no need for it really…
x399 is TR socket not intel
The connection from CPU to Chipset on both intel and amd is x4 3.0 lanes
Ah sorry assumed it was intel socket 
Yeah good old shitty chipset naming confusion
It actually seems like there will be a x399 chipset from Intel lol
PRIME X470-PRO AMD X470 is what I am considering, The second full size slot is quite far down so that should work fairly well I think.
Still not sure if my layout will look decent though, something seems off…
BTW this is not a flashy build, in fact I will probably add dark film over any leds. This is more about silence at reasonable temps at load (95% of the time at near full load due to either gaming or crypto).
Another option would be to flat mount the rads, just something to keep in mind
That’s what most wall pcs seems to do but I don’t really get why. It would require very thick backing and airflow would still suffer, maybe not as much as I would think but still…
In the interest of usability, why do you want the motherboard and GPU IO to point towards each other that close together?
The IO ports don’t have to point to each other but it’s nice as then both IO ports can be routed via the same cutout. I think I will try and upload the sketchup file after all in case someone wan’t to move things around, it took forever with my dsl net…
I’ll give you my take on this:
-
Rotate the motherboard 90° so that the I/O panel face the bottom part. My idea is that this way you’ll make cable management easier and will also be easier to plug in more peripherals
-
If you’re not going to use more PCI slots install the GPU over the other slots, like the vertical GPU mounts in new cases. This will make the whole thing more compact, keep the cables going in one direction and fill up the empty motherboard area
-
Move the SSD and the PSU in the “top area” So that the cable lenght needed to power all components can be minimal
-
Rads both can stay one on each side or both on one side, I leave it up to you
I know it’s a big overhaul on your idea but that’s what I came up with seeing your project. I hope you’ll find interesting what I proposed. Hope to see the finished photos of the work!
Something like this?
It does look a bit cleaner though I don’t like cable routing so close to the bottom. I won’t be plugging anything directly into IO and I don’t want cables hanging straight from the mobo.
I’ll probably do a ghetto build with rope/zip ties first and see how it works out. I am also thinking sealed build might be necessary to prevent dust build up though that’s for the final build if I ever finish it

Oh wow, I didn’t expect you to replicate it in Sketchup. Yeah, that’s what I was thinking about.
Sure all the cables hanging from the motherboard should not be a problem since I see you’re making a hole in the plate to have them hidden away. Also I think having them go basically straight down looks cleaner because they’re not bent up and than down. But I know it’s personal preference so it’s again just my idea about it.
Also to have all the cables going down from the I/O side to the PC a flat and wide cable channel might be a good idea (not thicker than the spacing you’re going to apply to the plate that holds everything from the wall)
I am making a whole bunch of layouts to see what looks best. It’s pretty easy once you get past the weird design of Sketchup. Feel free to download the project file and mess about with it.
Well the cables would only bend down towards the backing plate regardless of which way the IO ports are facing.
The channels can’t really be very thin as they have to be large enough to fit the connector. I suppose I could route out a larger opening behind the component and only connect it with an opening large enough for the cable. This might be worth it for the AC power connector.
