I've been thinking of making a new computer lately, mine is finally showing its age a bit. My current computer right now is: Antec P180B Case Intel Duo 2 Core E6420 2.13Ghz LGA 775 4GB (4x1GB) OCZ Reaper Edition DDR2 800 MSI P6N Platinum LGA 775 Nvidia nForce 650i ATX Motherboard Zalaman 9500 AT heatsink EVGA 8800GTS 640mb Antec True Power Trio 650watt PSU 320GB 7200RPM Seagate HDD The new computer I am thinking of making is: Antec 902 V3 Case Intel Core i5-2400 3.1GHz quad core 8GB (2x4GB) Corsair XMS3 DDR3 1333 MSI P67A-GD53 (B3) LGA 1155 Intel P67 ATX Motherboard CORSAIR CWCH60 Hydro Series H60 liquid CPU cooler EVGA GTX 460 Super-clocked 1GB 256-bit GDDR5 CORSAIR Professional Series HX650 650watt PSU Western Digital Caviar Black 500GB 7200RPM HDD (thinking of gettting a second one, and a 64GB SSD later on) So do you guys think I should upgrade, if so should i keep my old P180B case with the old PSU? I am looking for good airflow mostly in a case by the way.
