I am in the testing (2 weeks in, with no problems) phase of my new SB control computer. Using a dual core Intel Atom processor on a mini ITX form factor mobo. Dual 80Gb hdd, 4Gb ram,(XP uses 3) USB 3.0, DVI-D & HDMI out, 6 ch audio. Mounted in a 1.3U rack chassis that measures 17w x 2.5h x 10d.
These are normally passively cooled, but I added 3 interior fans to ensure great cooling. Makes 7 total with the PS fans.
Mounted it into a black melamine box that holds the computer and my SB Link sheet and label printers. Not shown is the plexi slide lid that covers printers when not in use. My old desktop 27" monitor was starting to burn in from the desktop, so it was converted to SB use.
Box is bolted to the top of a cheapie rollcab that will hold bits, wrenches, all things ShopBot.
Performance is not up to the level of my Core i7, but way above the P5 quad core it replaced. 37 sheet twd nests in 11 seconds. (the link guys will understand)
Heres a few pics:
