I just ordered this >> http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=9849937&CatId=2627 and I'd like to know if I can put a 700w Power supply, and a PCIe 2GB gForce 970 video card and I'm putting 32GB of memory. It's for my grandson playing Leage Of Legends and other games.. mostly for his 9th grade school assignments.. I'd like to "combine" the system..
