There's just something about this line of thinking that really irks me. Could you repair a transmission yourself? Could you paint your entire house? Could you tile your own floors? Assume the answer is "YES" to those questions, now further assume that although you knew how to do all of those things, and could save considerable penny doing it yourself, would it really be such a disservice and a ripoff to have it done professionally by a reputable company?
Yes. That 20thousand extra dollars that it would have cost me to hire someone to do all those things went into my retirement fund. Its called being wise with your money.
I mean, there's this overwhelming lull of posters here who just cringe at buying PC's just because they have the knowledge of building them, I don't understand it, it's like some weird movement. I know how to do my laundry, guess what, I pay to have it done, because of convenience and not having to worry about getting it done.
Well to be honest, you posted this on a computer building and overclocking enthusiasts board which is why you are finding hostility towards the markups alienware is offering. We do actually have a general hardware section of the forum which would perhaps be better suited to answer this question as there are a lot of custome made pc vendors and buyers that hang out in there.
