FWIW, I've been running Debian Wheezy on a Seagate Go Flex Net
(STAK100 - http://projects.doozan.com/debian/) for a while, with pretty
good results. It's a Kirkwood system with 128MB RAM, 256MB NAND, 2 SATA
connectors, 1 USB port and Gigabit ethernet
(http://archlinuxarm.org/platforms/armv5/seagate-goflex-net), and it's
perhaps surprisingly capable. It was a little fussy to set up (there's
some funkiness with unlocking the bootloader and getting it to
recognize and boot from SATA), and the SATA ports aren't physically
well designed for holding non-Go Flex brand drives, but once you get it
set up, it runs quite well, is very quiet, and has (I believe, though I
haven't measured) very low power consumption (I've seen figures of
between 5-10 watts). It runs about $40 (without drives) on eBay.

Probably good advice, but the plugs are tiny, quiet and very low power
(and cute and fun to play with, although certainly fussier and less
powerful and expandable than x86).
