Thanks for the bad news. I was hoping to get by with the stock PSU. I guess I will add that to my list. Any ideas on PSU/Video combos that work well with this machine? I really like the HD5770 but the cooler looks huge. I have only seen pictures of the inside of this machine and it looks like the CPU fan might be crouding out the PCIE slot. I will have a better idea when I receive the machine.
