It doesn't really matter if you paint your pc case all over. The ground is already taken care of by the psu. The acrylic case pc for example which is made of plastic. So paint away my man, paint it hot pink. :D

Chucks right, the PSU should take care of all that... Case really doesnt have anything to do with grounding, as that would be a MAJOR safety issue...(Imagine youre touching the case when the video card decides it needs to ground thru the case....ow) :D

Just helping to confirm the facts...yes, it's OK to paint the interior and exterior of the case. Grounding is handled by the PSU. Make sure you post some pics of the finished product!!!

Actually you're wrong. Cases are designed to join to the ground plane of a motherboard, through the standoffs. Of course this is meant to reduce RFI and the grounding is redundant.

In a perfect system the outside of the power supply grounds to the case as well as the ground plane on the motherboard, resulting in the least possible RFI, but heck, nobody cares, and careless people even make Acrylic cases.

The vast majority of PC power supplies tie the motherboard and peripherals to earth ground through the black ground wires, but a few don't because their black wires are kept separate from earth ground inside the supply, except at high frequencies. With such supplies it's important for the motherboard, drives, and supply to all be grounded well to the computer case, and it's possible that a good paint job will prevent this. Old IBM or Mitsubishi desktop cases were masked off before painting to keep the metal bare around the screw holes, so I would remove the paint there or at least take ohm measurements to verify low-resistance grounding.
