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.

[–] [email protected] 16 points 1 year ago (1 children)

I was thinking just put a roof over it like a bus stop but I remembered that dust works differently than rain.

[–] [email protected] 5 points 1 year ago (1 children)

my tarp-wrapped tower has never once gotten water damage, strangely enough i keep having the replace the cpu tho

[–] [email protected] 2 points 1 year ago (1 children)

You’re right on the line between this being a joke and someone actually being serious.

Good job, I’m confused and scared.

[–] [email protected] 1 points 1 year ago (1 children)

I think I'm going to try for a distilled water submerged build. DI is not conductive, right?

[–] [email protected] 1 points 1 year ago

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.

[–] [email protected] 13 points 1 year ago (2 children)

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.

[–] [email protected] 4 points 1 year ago (1 children)

We sweep our floors every day and vacuum twice a week and I need to clean my tower dust covers every two months.

[–] [email protected] 1 points 1 year ago (1 children)

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...

[–] [email protected] 1 points 1 year ago

It really depends where you live. Some places are very dusty, especially if it's generally dry and/or windy.

[–] [email protected] 1 points 1 year ago

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.

[–] [email protected] 3 points 1 year ago

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.

Why do you want to hide this piece of art?

[–] [email protected] 14 points 1 year ago (2 children)

Because it looks good now but will look like a mess with all the cables necessary to actually use it

[–] [email protected] 4 points 1 year ago

Power and displayport are the only ones you need. Get white cables and route them to the back

Thanks! I can still see it from the side lol

[–] [email protected] 15 points 1 year ago

Looks nice. I would look into getting custom length cables to clean up the look a bit.

[–] [email protected] 15 points 1 year ago (2 children)

Is there enough airflow on the backside of the GPU?

[–] [email protected] 11 points 1 year ago (1 children)

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.

[–] [email protected] 3 points 1 year ago (1 children)

While that’s true for the card in the image, flow-through GPUs absolutely do exist - Nvidia FE cards, particularly.

[–] [email protected] 2 points 1 year ago

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.

[–] [email protected] 2 points 1 year ago

There is a 20mm space from the GPU’s backboard to the pegboard, should be enough

[–] [email protected] 11 points 1 year ago

This is art

[–] [email protected] 9 points 1 year ago (1 children)

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.

[–] [email protected] 2 points 1 year ago

Yeah IKEA also has a gaming line, however nothing about a gaming PC

[–] [email protected] 6 points 1 year ago (3 children)

Does it affect performance that the gpu is connected with that long of a cable?

[–] [email protected] 21 points 1 year ago (1 children)

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.

[–] [email protected] 10 points 1 year ago (1 children)

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

[–] [email protected] 8 points 1 year ago

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.

[–] [email protected] 6 points 1 year ago (1 children)

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.

[–] [email protected] 4 points 1 year ago

I think OP was more concerned about latency than throughput.

[–] [email protected] 3 points 1 year ago

Nope. As long as your signal still gets through without timing issues, everything behaves fine.

[–] [email protected] 5 points 1 year ago* (last edited 1 year ago)

Some custom shortened PSU cables will take this to the next level.

[–] [email protected] 4 points 1 year ago

Looks nice mate, good work

[–] [email protected] 3 points 1 year ago

You could say you are a pegboard nerd

[–] [email protected] 3 points 1 year ago

Oooh nice I've been wanting to hide my big living room PC, never considered behind the TV.

[–] [email protected] 2 points 1 year ago

This reminds me of the look of the thermal take core p series.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago) (1 children)

How is the noise with this setup? The CPU cooler looks undersized for the amount of space you have.

[–] [email protected] 1 points 1 year ago (1 children)

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

[–] [email protected] 1 points 1 year ago (1 children)

Hows the hotspot temp on the Gpu. I have a 7900xtx with the same cooler design and without airflow the backside gets super hot.

[–] [email protected] 2 points 1 year ago

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.

[–] [email protected] 2 points 1 year ago (2 children)

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.

[–] [email protected] 4 points 1 year ago

May I ask why you went with mini-itx?

A S T H E T I C

[–] [email protected] 4 points 1 year ago

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

[–] [email protected] 2 points 1 year ago

this looks good, I have saved another peg board 3d print set and plan to do this eventually. I have the board and a printer, its just the time to mess around and try to mount it as its technically custom depending on your PC setup. Just not sure I can manage with the downtime whilst I fiddle with Starfield out and party animals later this month :D

[–] [email protected] 1 points 1 year ago (4 children)

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?

[–] [email protected] 6 points 1 year ago

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.

[–] [email protected] 5 points 1 year ago

I run a SFFPC and it's really common to have a pcie riser just like that. Performance differences are minimal verging on unnoticeable.

[–] [email protected] 4 points 1 year ago
[–] [email protected] 2 points 1 year ago

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.
