I'm trying to build a nice reliable gaming computer. So far I have an asus z87 pro motherboard, a 4670k processor, an evga superclocked gtx 770, a standard hard drive and optical drive, and an h100i cooling system. I was wondering if it reliable to go for a cheap case / psu (such as http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=8324228&sku=M69-0204) or should i go the extra $200 and buy a corsair 300r case and a corsair 750w PSU. Thank you.
