Caution: Don't do this at home unless you know about the risk of shocking yourself even after turning it off! If you want to take that risk, Always discharge those 1 or 2 large mains filtering capacitors by jumpering the green wire in the 20 or 24 pin ATX plug to a black wire in the same plug while the PSU is unplugged. You should hear a click. Remove the jumper and disassemble.
