I bought a couple of barebones pc boxes before getting this one, but none of them seemed to support legacy MBR partitioned disks, only UEFI. And I need that support (CSM or legacy) cause I have a disk from a dead linux machine, and I don't want to reinstall OS and migrate the software etc. This one works, is very quiet, doesn't overheat so far, has 4 usb 3.0 ports.cons: the blue light on the front panel is annoying. But I guess you can put a tape over it.EDIT: no need for tape, all lights (intensity & color) are controlled via BIOS
