Question Can you put these together?

4.3L is impressive, but if you are putting a GPU in there, I don't see how there would even be enough internal volume to put it in, let alone mount it to anything.

A high end AMD APU, and could maybe rig something up using the PCIe expansion brackets, but I doubt that is what you are going for. (And at that point there would be plenty of room for a taller CPU cooler)
 
They hve AIIOs that go in PCIe slot right? Maybe that can go on the other side of the tray instead of a GPU. Wpuld be nice to figire out to get a AIO in it.

I don't think as a normal product generally. There are a few specialty brackets out there.

But at that point, you could easily get more surface area from a regular heatsink.

Also several 3D printable adapters. Most are intended for adding an intake fan via the expansion slots to feed a GPU.
 
I have a Ryzom 7 2700 in it now, that is prob. all it can take. I would be very happy if I could put a 5800x in as is & it would be fine. I would love to email Joycom about an idea for a wider (5' so a SFX would fit, deeper proob 7.5 so 2 fan GPUs would fit, but they don't have a page, so no email options.
 
5700X has a lower TDP, the better choice.

Plenty of chassis out there that take an SFX power supply under 10L, some are more expensive than others.

I'm quite pleased with the NR200 I put my old 4770k into. I have a decently tall thermalright cooler on it, though the fan doesn't quite fit. Not a big deal I have that system underclocked.

I hastily put it together last year for a retro lan party. A bit overkill for Quake III and Unreal Tournament, but it got the job done.
