I wanted a media center/home server, so, I built a AMD six core system with 16GB of ram, 120GB SSD and twin 2TB HD mirrored, running Win7 Ultimate, about a year ago. It's the best Windows machine I've ever owned and yet it's still flakey enough at times that I hate I didn't get a Mac. Unless something amazing happens I will not have another Windows machine. All Apple from here on out.
