Also, I hate to be that guy, but if you are trying to compete in this market, why even spend time doing a Desktop computer. It is a super shrinking market... the only folks that still buy these are gamers (where sadly you just have to live with the proprietary stuff to squeeze every cycle for performance) or something hyper niche that doesn't matter anyway.
Concentrate on one product (probably laptops) and make something outstanding there. There are some of us that want to buy it.
