I built a system around a 3U chassis, then tried to stuff a GPU in the box and couldn’t close the lid. I got a 4U chassis and rebuilt the system, but I still have the 3U and I’m thinking about filling it back out so I have a failover for Proxmox. Is there a GPU I should consider or just stick with the integrated graphics? I’m currently only using the GPU for Steam remote play using pass-though to a Windows VM, but Jellyfin, Frigate, Immich are on my to-do list.
You could look into low profile GPUs. Off the top of my head, the 3050 is probably the strongest of those, unless you’re willing to look into the A-class cards
