No matter where you buy a Fujitsu-Siemens PC from, it's going to be right load of bab

I'd go for a Dell, or an HP Business Desktop

I install loads of these and they're rock solid, and unlike the dell's, you can upgrade them yourself when the time comes. Dell machines dont have any additional HDD bays or anything

The HP home stuff is still rubbish though, pavillion and compaq series etc
