Despite being a Server, this is actually my main workstation. It just bought a server unit because I needed a RAID subsystem and opening up a mac to add/replace drives would invalidate the warranty (which has long since expired anyway, but wasn’t an enticing prospect when it was brand new). As for Ubuntu or another Linux distro, I do use Linux and DragonFlyBSD on my servers and to host my Mathematica grid.
