As a fellow muller, I've looked into the Shuttle xpc Zen. It has an
external powersupply, a la the apple cube, and is extremely quiet
according to the people of www.silentpcreview.com
. Right now it only
comes in a pentium 4 flavor, but they may release an AMD version. It's
biggest flaw is the lack of an AGP slot (it has builtin nvidia, and 2
pci slots, I believe). That wouldn't be any problem if you don't run
any really graphics intensive games.
i'm currently mulling over the idea of getting one of those really small
shuttle xpcs for use as a quasi-portable linux-based audio box/desktop
replacement, and was wondering if anybody had used them before and had
suggestions or encountered caveats/hardware problems/quality control
issues/etc. apparently the amd-based systems use an integrated realtek
audio chip that is supported under alsa, but i'd probably put a better
audio interface in the one available pci slot anyways.
