So, here's the thing: I'd like to build an equivalent to a mid-range or so gaming rig with unraid for two players. One of us will probably be playing via somthing like "Parsec"... Problem is, i don't even know where to start ! I'd like at least 8Gb of Ram par players (32Gb total) and the capacity to upgrade gpus if needed later on... 2To of total storage is more than enough. If possible, i'd like to keep the total under 2000€... Any help would be appreciated, thank you :)
