This sounds very interesting. I've been looking for a reasonably powerful, yet compact and silent gaming rig for a while (not too far from a mac mini size-wise)

This sounds very interesting. I've been looking for a reasonably powerful, yet compact and silent gaming rig for a while (not too far from a mac mini size-wise) . I had ignored the nucs assuming they'd be too compact and therefore very noisy. What kind of gpu did you put in it?
