Here is a good deal not to pass up. Small net-top AMD APU E-350 barebone computer.
It is currently $120 ($110 after rebate) with 64GB OCZ Agility SSD at NewEgg.
It is the size of a few DVD cases (19 x 14cm and 2.5cm tall). It supports one 204 laptop dimm and a 2.5" laptop drive. The power draw is 14-23W (idle to playing video).
It comes with a SSD and I have a few laptop memory lying around. At $110,why not?
It is $110 after rebate today: http://goo.gl/DULcp
