Building a cheap PC

There is a lot of people out there who like to build computers. I have built a couple over the past few years and it seems even though the hardware gets better it also seems to get more expensive. so over the past few days i will show case some pc parts that are on the cheap. so for this first post in the series lets start with the motherboard. Currently the cheapest motherboard processor combo. The Intel Atom (the same one used in the "hip" netbooks) is very cheap and cabable. the Foxconn 45CS which is roughly $60 at newegg. it is a mini itx motherboard which is on of the smallest you can get. the atom is also compatable with every major os. but currently osx leopard not snow leopard supports the atom.
