Pogoplug for $20 (free shipping)
 

It looks like they're getting rid of some of these other arm devices for cheap now that raspberry pi is almost out. $20 for a dual core ARM device or 1.2ghz single core device that has *nix support via multiple distros seems like a pretty nice deal. :thumbup:

Make sure to sign up for the "friends with benefits" dealy on the site to get the $20 price and free shipping.
