160GB network drive for £19.99 plus postage (which generally seems to be around £3 from this site)
This seems to be the same network drive housing I recently bought for this price, but now it has a 160gb drive ready installed - a pretty good deal. It worked very well once I'd got a firmware upgrade that let OS-X and Vista work with it.
I should mention that the boxes don't have USB ports, unlike some other network drive boxes, so you can only use them on a wired network.
Maybe I should also mention that the_magician was still waiting for a computer he'd ordered several days ago the last time I looked. Don't know if it has appeared yet.
