Be very careful! Dell owners may not realise that many Dell motherboards and power supplies (PSUs) use non-standard wiring. The connectors are the same, but they are wired differently. This means that if you put a non-Dell motherboard in a Dell case with the Dell PSU still there, and try to power it up, when you press the power switch, you may destroy the motherboard.

So you may have to change the PSU at the same time. Therefore, you may think it is a better idea to sell the Dell and buy a new set of parts, or remove the disk drives etc from the Dell and use them again.
