i bought my a1020n for $650 plus a rebate for like $150 off, the initial cost for everything in the end excluding editing programs was about $1200, i get better speed and performance from this computer, if i was to buy a $1200 computer it really wouldnt compare, glad you decided to build a performance computer, it really is cheaper.
