Look at the PE 1850s from dell. They can be pricey but they are also dual xeon with all the goodies in a 1u package. Plus dell server support is usually top notch and I'm pretty sure each server comes with a 3 year warranty. If you wernt hosting so many servers on one machine I would say go for the PE750 line. They are single proc P4s though. Ive worked on both servers for sometime now and the build quality is superb. As far as the build out goes for the server its self I would say go with something like the following...

This will probably give you the power you need while having mirrored drives for data safety. There is an SC14XX something or another 1u server as well but I have never worked with one and from what I could tell you can not get a raid setup in them which means no mirror. That price also includes rapid rails to rack mount the server. f you dont need rails you could pobably save a couple hundred bucks. Ive never tried to build a rack mount server on my own so I'm not sure what the cost would be but I would venture to say you will not come close to this if you factor in support and build quality. One last note I did not include an OS in this purchase but if it were my CS server I would run it on linux anyway. Just my 2 cents
EDIT: If you are looking for more then 1 or 2 I would contact dell. They do cut breaks for an order of multiple servers.
