I upgraded my gaming machine and used my old motherboard and cpu and loaded unraid on there, the i7 was great for plex transcoding and eventually i ran out of sata ports on my machine so I stuck a sata expander card in my one pcie slot, luckily the motherboard had two m.2 slots so I used that for cache. the case I used was a node304 and over time I added drives as I was running out of space. eventually I build a separate JBOD chassis to hold more drives
