Thanks for the reponse. My other option is a refurbished Acer Predator with a monitor, mouse and keys for about $650(no warranty). I know the GPU is not great, but I can easily upgrade it.
Acer Predator AG5900-E3522 desktop
Intel Core i7-870@ 2.93GHz/ 6GB DDR3/ 1.5TB HDD/ ATI 5570
w/22" Acer LCD
How does this price/specs compare to the custom pc?
