Theres always ebay as well, you may be lucky! (There were a few floating about ebayUK a few weeks ago) Good luck finding one! Although now theyve got to 'Nano-itx' only 12cm square!
So a nice small linux distro on a nice small PC
have a look at www.mini-itx.com
I've finally done it, I've splashed out on a new case http://www.mini-itx.com/reviews/3688/
Cant wait till after my exams, so that I can set it up properly and play around with it as a web/file/games servers under linux
The case comes with a power supply, luckily the now 'spare' one goes well with my ham radio gear 
P.S.: Don't worry John I'll post pictures when its up and running.
