Lower power is ARM, but aren’t X86 CPUs not still a lot faster? (While my Raspberry Pi 4 can barely run a Minecraft server, my 50$ SFF can run 2 servers at the same time and still has plenty of CPU cycles left)
Power consumption is higher ofcourse, but I exchanged 3 Pi’s (3*10W) with one SFF (25W) so it’s fine :-)
