I am about to buy a new graphics card (EVGA 01G-P3-1460-KR GeForce GTX 560 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI Support Video Card) and a new power supply (SeaSonic S12II 430B 430W ATX12V V2.3/EPS12V 80 PLUS BRONZE Certified Active PFC Power Supply) for my "DX4860-UB33P" but im not sure if they will fit into my case or if I need anything els for it like a cooling system or something. Im also buying these for gaming so if you could tell me if its a good idea i will gladly appreciate it. Thanks!
