The products used for the build are they good quality/trusted brands? For example I wanted to know what make/brand of gtx 570 they use because I am considering buy it separately and installing it myself.
nvidia cards tend to be mainly palit but sometimes gainward and ati cards are normally powercolor. personally id always but the whole system from pcs as extra parts dont come under warranty of the system and thats what you pay for with PCS awsome support.
