My case was purely, that I had upgraded the gpu in my classic Mac Pro, and thought that a SFX pc build could be done with the old gpu and a power supply and mobo. It started out with a cheap mobo, to hold only an old i7 from an imac that was parted out, and 8gb of ram (2x4 sticks I had spare) and the vega56. I found it so capable a system, that the only issue was ram when I forgot about the dozen tabs open on a browser, and the game just launched would hang the system. Before I would ‘waste’ spending money on the max 16gb that this board could hold, I started collecting the parts for it’s current setup; a520i, ryzen5 5600x , 64gb, nvme ssd and the gpus I’ve now swapped between the cMP so now it’s a rx5700xt. Use is purely a spare, don’t want a windows machine, I’ve got the mac for a server/media machine, so it’s all purpose and games on the Linux box. Although I have got dual boot capability set up on both just because I could, maybe something really offside would need w10 - one example; VCDS car diagnostic software that doesn’t support anything but win.
