Thin mITX with discrete graphics options?

post #1 of 23
Thread Starter 
I have been wanting to try doing a small build, as minimal as possible and no wasted space. I particularly like the thin style PC (you guys can keep your cubes), but something has recently caught my eye.

Thin mini-ITX has popped up on my radar. It's originally designed for all-in-one PCs and is the same dimensions as mITX but the I/O is half the height. More importantly, though, the board components only go up that high, which means I can stick other crap up top without making the PC thicker, and I find this appealing (see another project around here where someone stuck a videocard in that space with a custom riser. shineh). What I don't find appealing is that I can't seem to find anything that might let me stick an actual GPU somewhere (Intel HD graphics can die in a fire), so I am invoking the power of MOAR EYES.

Has anyone seen any thin mini-ITX board with either a PCIe x16 slot (or at least an x8) or one that has a slot for an MXM module? Intel claims manufacturers make boards with MXM slots, but I can't seem to find any.

Am I just going to be stuck trying to jury rig a card into the crappy x4 slot?

Dat Core2 Duo power.




Also crazy Russians.



There was also one Gigabyte board that was Thin-ITX with an x16 but they only sold those in mass order quantities.



Unfortunately you'll have to probably use an x4 to x16 ribbon cable. But hey! x4 3.0 = x16 1.0 tongue.gif

I heard about the Gigabyte one. I also saw the AIO they put it in, and it was stupid thick because of how the GPU fits in.

What's the first one?


I saw a couple boards by someone named Wibtek, but I've never heard of them before, so no idea if they are any good. More problematic is I haven't been able to find who sells their stuff, not even OEM suppliers.

Crazy Russian board is not what I'm looking for since it's not th form factor I'm looking for.
Again, seen the gigabyte board, but the way the card goes in is kinda stupid.

I saw a couple of boards made by someone called wibtek, but no idea where to buy one. Is there ANYTHING out there that isn't OEM only and stuck in a pre-built AiO PC, or at the very least, anyone know a place to snag normally OEM only stuff?

Don't know if you saw it, but I recently experimented with powering a thin mITX board (GA-Q87TN) and a 970 off of a regular internal PSU.

Just x4 there, but it's PCIe 3.0, so not only is the performance impact going to be quite low, if noticeable at all, but gigabyte also was wise enough to use an open-ended x4 port so you can just put an x16 card in without problems as you can see here.
You can also see just how thin a PC can be made that way.

x16 is on no retail thin mITX board because it would require the onboard voltage regulators to supply 75W on that. So yes, you'll have to stick with x4, sorry. You could just write to the wibtek guys and ask them, they should know if they have any distributors. Next challenge will be finding an MXM card.

I hadn't seen that no. Thanks for the link. I did see http://www.overclock.net/t/1536159/build-log-h2o-micro-sub-3-liter-custom-watercooled-gaming-rig/0_50 though. My main concern with either of those prospects has been how efficient the GPU would be with only 4 PCIe links. The fact the GPU remained off until the motherboard started up is good news though. I had another thought for a project that would involve a 12V only power supply feeding a GPU and a picoPSU (since the PicoPSU alone can't handle a GPU being added generally).

Anyways, while difficult, I have still noticed a couple places I may be able to source an MXM card from since they were originally designed to (theoretically) give stuff like laptops expansion options.
It's the motherboards that I'm having trouble with. Probably because it's a very recent development in a niche market.

There is a thin itx board with x16...

but it's not exactly super popular. It's H61 too.

This guy here is using it out. Haven't heard from him in a while though.
post #9 of 23
Oh yeah and x4 3.0 is enough for pretty much all graphics cards right now (GTX 980, R9 290, etc).

There was a test somewhere that documented a minimal loss of frames in game, but don't know where that is...
post #10 of 23
Looks like the H61 chipset supports Ivy Bridge processors, so you could slap am i7 3770K into that board. But it also looks like the spec only supports PCIe Gen 2.0. So, wouldn't that bottleneck the card?
