Thanks,
I looked around, but there are too many incompatibilities with m2 ports, and graphics cards.
Starting from driver issues, to issues with cabling.
I checked out the fractal design node 202, their smallest case, but it's nearly the same size as a Dell desktop PC, so I returned it!
In the end, I had to settle for this rosewill case:
https://www.amazon.com/gp/product/B004Q7J1S0/
It only fits a single slot graphics card, but with some serious frankensteining, like cutting, bending and drilling, I was able to fit a Zotac 2070 Blower type of card.
It all fits perfect, save for the motherboard, that needed separate mounting holes, and the backplate I needed to cut 1/2" of material off.
I now own probably the first and only $50 motherboard, $50 CPU, $50 ram, $24 SSD, $10 dual 8cm fans, $50 rosewill case with a 2070 mounted in!
Even the CPU cooler, I had to remove the fan, because it wouldn't fit. So the CPU gets passively cooled, through one of the Case fans, and the PSU fan.
It's truly a frankenstein monster inside, but from the outside one can only notice some minor cutting in the back,and a power supply cable hole on the top cover.
The rest looks totally stock; fits in a backpack.
If I try hard, it will still have room inside for a DVD disk drive.
It runs cool. CPU reaches about 70-77F under full load; well within throttle limit.
GPU reaches 80F under 100% fan load and 175Watt. Once I start overclocking, it can reach temperatures of 85F with 100% fan speed.
I'm looking to drill some holes in the side of the case, for better airflow.
That GPU in an open case, reaches 77C with 66% fan speed, or 66C with a 100% fan speed. So in a tiny case like this, it could go down by a good 10C the least!
GPU fan sucks air out of the case, and helps CPU to cool down by a few degrees, to 70-74F.
Overall it's a very stable system. Great for gaming (100+ FPS heaven benchmark).
I just wished it was a tiny bit smaller. The size is good, but it's more shaped like a toaster than flat; as the card and the motherboard are perpendicular, rather than parallel.
