I designed 3D printed components to mount my ITX + 3080 + SFX to an IKEA Skadis pegboard, so it can be wall-mounted behind my TV.

That’s cool, but I can already imagine all the dust it’s going to accumulate.
I was thinking just put a roof over it like a bus stop but I remembered that dust works differently than rain.
my tarp-wrapped tower has never once gotten water damage, strangely enough i keep having the replace the cpu tho
You’re right on the line between this being a joke and someone actually being serious.
Good job, I’m confused and scared.
I think I’m going to try for a distilled water submerged build. DI is not conductive, right?
For the sake of the joke, yes. As long as the water remains pure. But once some of the material starts to dissolve into the water, then it’s no longer safe.
Depends in how clean your room is. I have a case without dust filters and it’s been running for over a year without any visible dust accumulating.
Also it’s mounted up high, the further you can get from your floor the cleaner it’ll be.
We sweep our floors every day and vacuum twice a week and I need to clean my tower dust covers every two months.
Wow, we only vacuum once a week, that’s it. Maybe its because my tower is on my desk? Or our air is just really clean for some reason…
It really depends where you live. Some places are very dusty, especially if it’s generally dry and/or windy.
Getting it off the floor helps a lot. I used to work in an office with carpet, and when we got new PCs I sat the keyboard box on the floor and put the PC on top of that.
Might not be that bad. My computer picks up way less dust sitting on my desk surface than it did when I had it on the floor, and I imagine OP’s TV is mounted at least as high as that.
I’m personally worried about the GPU’s heat harming the wires over time. I would’ve mounted it vertically, but I’ve never seen custom extensions that do that.
Why do you want to hide this piece of art?
Because it looks good now but will look like a mess with all the cables necessary to actually use it
Power and displayport are the only ones you need. Get white cables and route them to the back
Only a video cable + a wifi antenna for now. The power cable is on the other side and is hardly noticeable.
Thanks! I can still see it from the side lol
Looks nice. I would look into getting custom length cables to clean up the look a bit.
Is there enough airflow on the backside of the GPU?
You don’t really need any airflow there. The only thing that gets hot there is memory, but that is already cooled through the PCB (good heat conductor because of the copper), which is cooled by the regular heat sink.
While that’s true for the card in the image, flow-through GPUs absolutely do exist - Nvidia FE cards, particularly.
Yeah but you can see in the picture the GPU has spacers. The riser cable goes under it and you can see where the rear IO sits that there.is space there.
There is a 20mm space from the GPU’s backboard to the pegboard, should be enough
This is art
Very cool, I love how the mounts you created match the ikea aesthetic.
It would be funny to see Ikea themselves implemented this in their home office line.
Yeah IKEA also has a gaming line, however nothing about a gaming PC
Does it affect performance that the gpu is connected with that long of a cable?
Adds about 1ns (nanosecond, a billionth of a second) per 30cm of riser. So essentially nothing. The only problem happens when some of the signals are lost / attenuated / confused due to interference. As long as it’s a high quality shielded riser it’ll be totally fine.
I am not fond of LTT so I won’t link their video - but they did a 1.3m PCIE extension and measured no performance impact at all. I’m sure OP is fine.
I am not fond of LTT
Same. Been telling the algo on YT to ignore LTT related videos for awhile now. Used to get recommended like every other day or so. But lately the algo has been deprioritizing their vids. Maybe the latest controversy (employee abuse) had something to do with it
He’s just kind of a jerk. Was honestly not all that surprising. I wouldn’t want to work for him… Also I’d never want to trust the reviews or opinions of someone who can’t take criticism well.
if the riser is rated for 16x you shouldn’t have any slowdowns.
you can always check if the card is linked at full speed. if it’s at 16x, then there’s no difference.
I think OP was more concerned about latency than throughput.
Nope. As long as your signal still gets through without timing issues, everything behaves fine.
Some custom shortened PSU cables will take this to the next level.
Looks nice mate, good work
You could say you are a pegboard nerd
Oooh nice I’ve been wanting to hide my big living room PC, never considered behind the TV.
How is the noise with this setup? The CPU cooler looks undersized for the amount of space you have.
CPU fan can get noisy at full load. Could use a better cooler, this one is just what I already have and is okay so far
Hows the hotspot temp on the Gpu. I have a 7900xtx with the same cooler design and without airflow the backside gets super hot.
The backside can get hot. With my previous setup (before mounting it), the backside is facing up exposed to open air, but it’s still very hot at full load. There is no performance issue though. I guess it’s designed like this and it’s totally normal.
May I ask why you went with mini-itx? There looks to be plenty of room for at least a micro-atx, which would probably be cheaper and have greater expandability. Great job anyhow.

Good question, it’s mererly because I was using an ITX case with those hardwares, but it’s not easy to fit the case behind the TV, so I came up with this solution. If I start new, I might choose ATX instead
This reminds me of the look of the thermal take core p series.
I’m curious about the effects of the added physical distance with a PCIe extension like that. Presumably it adds a tiny bit of latency across the wire. At what point does it become an issue?
it’s only a problem if there’s enough interference to prevent the card from linking at 16x with the pcie bus, otherwise lightspeed won’t have measurable effects at that point, there’s no processing done by the riser.
I run a SFFPC and it’s really common to have a pcie riser just like that. Performance differences are minimal verging on unnoticeable.
Not for a considerable distance:
The latency isn’t an issue, the timing becomes an issue because you don’t have a clean signal at some point, meaning the signal will arrive “spread out” over time. If it spreads to the next signal, your GPU isn’t recognized anymore.
But as long as.that doesn’t happen, there is no latency or performance decrease.
