You might get some info from dell tech support. But I would consider only upgrading the cpu, or use the pc for a spare. Dell boards have a special connector for the power switch, led's, and reset switch. You can get a "bare bones" setup with case, mobo, cpu and heatsink for less than trying to match anything with your dell case. The power supply is also too weak at 200 watts for any newer cpus and video cards.
