never buy a desktop from a large manufacturer (dell, hp, compaq, gateway etc), they always rip you off on parts. goto
www.canadacomputers.com and you can get a very good desktop for half the price.
only goto large manufacturers for stuff like laptops.
the reasoning is that a desktop is made from off the shelf parts, you can buy them separatly, put them together and save 400 easy. if you get them as a set system they almost always add OEM (licensed replicas) parts and the general build quality is horrible. plus they try to tack on stupid things like to the door service for an extra 300 or anti-virus for an extra 150.
if u have any more q's pm me, i'll guide you through the process.
