A 3U case can support full height cards. Anyone have a favorite 3U rackmount PC case?

The only I've used and like goes out of stock regularly though.

I have a 4u, not a 3u, but sliger has one now that should be pretty good. https://www.sliger.com/products/rackmount/3u/cx3151a/ has a riser for doing a modern (heh) sized graphics card.

That looks cool, but no HDD backplane.. where do you put the drives?

They have variations with cages if you need them. They're great!

Sliger makes good stuff I have their SM550 SFF case and it was really well put together, makes heck of a compact machine.

When I built my most recent home GPU server, it seemed like 3U wasn't tall enough to fit a big GPU upright, given the PCIe power connectors on top of the card, so I went 4U.

Though I think you could get a double-wide GPU into a 2U with a PCIe riser cable/card.

heck, you'll have difficulty fitting a 4090 in a 4U without special right-angle pcie power connectors

For 3U/4U I like iStarUSA cases. I went for 4U for the quieter 120mm fans and so it can fit half-hight bays sideways on the front panel. Here's my video encoding workstation in an iStarUSA D-400L-7SE: https://imgur.com/a/YLjDX0e

I just bought a iStarUSA D-300 and I was disappointed that there were no easy mount points for 2.5" SSDs.

I just mount them to one wall of the case with double-sided adhesive tape lol

You can also spring for their matching drive bays http://www.istarusa.com/en/istarusa/product_speclist.php?ser...

Like others here, I usually go 4U. I've been fairly happy with one of these; I like that the whole front is just fans.
