We used to run dual processor liquid cooled gamers buying ram buy the box, it got too expensive and took to much screwing around to make it worth keeping up. Console systems are easy to use but become outdated and still cost less than competing to have the newest fastest computers. Atleast with a console you have the newest fastest for a couple years until the next version arrives.
Since I never bought an x-box I can put that money towards the new one and I'll also be able to start a collection without spending $60 a game.
