I installed it on an old series 3 chromebox (sandybridge i5 mobile chip) for a while. It's great, given how simple it is to setup and the amount of systems it can emulate.
Interface is a lot like the PS3. Copied games over FTP, it picked up a lot of the game art. Could also use my PS3 controllers wirelessly.
Performance-wise I didn't try anything past N64/PS1 but it ran everything really well.
