This is the machine that serves my [gasp] Audiotron. Unlike the Shuttle machines, it is quiet (actually almost silent) and cheaper. And it is much smaller. I chose the Eden CPU at 533MHz over the C3 at 800MHz because it was designed to run without a fan. You can run a C3 with just a heatsink as well, but I wouldn't want to trust it running non-stop 24/7 without one.

I bought mine from Caseoutlet.com. Available in black and white.
