Looking for cheap PowerPC based NAS/evaluation board

Hello
recently I purchased linksys NSLU2 and found that buying some NAS  (o
consumer device) seems to be the perfect way how to get evaluttio
board quite cheaply -- I'm software engineer, so I don't need all th
GPIO's contacts on board available, mostly I'm just interesting i
ethernet, serial for console and PowerPC processor (plus flash an
RAM). Anything available? So far I've found just

1) Synology DS-101g
2) CerfCube 40
3) Apple Mac Min

every evaluation board for PPC which I've seen so far was about 
$700 even if they call it "low-cost"
Thanks for any idea about cheap PPC system
Kare

Kuro Box (Buffalo Linkstation) is also an option, but Kuro Box is a bit
difficult to source in the USA at the moment - not looking good in the
long term either. However Linkstation is readily available, e.g. at
Amazon.
