|I realize the original 220 watt power supply is weak but I believe i can replace that with a 400 watt power supply from Tiger Direct.|
The new power supply would be an iStarUSA IS-1U40PD8 1U Switching Power Supply - 400W, 80 Plus, 40mm Fan, 24-PinItem#: I202-2382 | Model#: IS-1U40PD8
After replacing the power supply I would like to upgrade the CPU to the fastest one possible.
I would then upgrade the graphics to a VisionTek 900463 Radeon HD 6570 Video Card - 1024MB, DDR3, PCI-Express (x16), 1x DMS59, 1x Mini DisplayPort, DirectX 11, Single-Slot, Low ProfileItem#: V261-6574 | Model#: 900463 also from Tiger Direct.
Can I do this and if so what is the fastest CPU I can use?
