I've been hosting an Arma 3 server on my old phenom 2 machine, but wanted to do a fun build, so I picked up an 880g itx board and p2 945x4 proc on fleabay. 3d printed a mobo tray, HDD holder and a PSU bracket. All screwed to bottom of desk behind cross support for a hidden PC. OS install this weekend per kid's schedule. Gonna swap out the HDD with an SD too.
