Using a PC PowerSupply as a bench power supply.

I have the need to for a cheep 5/12v power supply and have a lot of
out dated PC(s) that I can rob the supply from, I just had some
questions about how to set it up.
There are some articles on on-line that discuss the subject but don't
really go into specifics like, if I need to draw current from the 5v
circuit to get the PS to regulate correctly, specifically how much
current do I need to draw ? Are we talking milli-Amps or Amps ?
Also, the power good signal. I understand that that the power-good
line must be held low, but these articles state just short it to one
of the ground wires. Back when I had circuits we use a 470ohm
resister to hold a logic signal down ? Right ?
How do I use the power reset ? Can I just place a momentary contact
switch in the PS case and use it as On/Off ?
Thanks
Sid.
