uhm.. the local computerstore??
Because if I go to the computerstore down the street here, I can tell them which mobo to put in, which pocessor, which graphicscontroller, which memory, which harddisk, even which case
So I think I would walk there..

But it could be this is a little bit expensiver than Dell's bulk computers,
At a local store the service is normally very good, waranty is also good here, completely customized, and also here you can try to get it some cheaper...
