No way...hell no...wow..thats a rip off....let break this down price per part:

After their cheapest shipping charge of $40 you are paying them $300 to simply put it together..install Windows...box it and drop it in the FedEx bin. Their "lifetime" technical support is just software call in. And their warranty is probably so full of clauses that if you even open the case to clean it you'll void warranty.
As always stated in this forum...it's always cheaper to purchase the parts and put it together yourself....you get a warranty with each part on it's own.
and Christmas time is not the best time to buy...if you notice on the bottom of the page I linked it tells you the history of price changes for the parts listed....Dec 1st all prices go up quite a hefty bit. Better to wait till Jan.
