My buddy and I are building a mining rig with 3 RX580's on a Gigabyte GA‑AB350‑Gaming 3 motherboard. The problem is a lot of these cases have the PSU on the bottom and there isnt enough room to fit all 3 GPUs. We need to finding a case that will allow for all 3 GPUs to be placed in it. Besides open air cases does anybody have any suggestions?
