I have a Dell Dimension 4700 I got for free and was wondering the best way to upgrade it to a gaming rig. I would rather keep the case and most of the parts I have i/e my 1TB SATA HD my 8GB of DDR2 Ram and such I just the Motherboard and a new CPU pretty much preferably a mobo with an on board video such as the ASUS M4A88T-V.

Your case will only accept a Micro ATX board not a full ATX so there is no go on that board. I would suggest though getting a mid tower case and transfer everything useful out of the Dell case to that rather than reusing it.
Yeah, a new case and PSU is good insurance for a successful rebuild!
