In the design of our new TwoLane
we were tempted to use computer power supplies, you can often find them real cheap. The few that we tested were found to be unreliable. I think someone else had mentioned they really want/expect a large current draw on the 5v and/or 3.3V output to be stable, the ATX version have an unfriendly electronic on/off switch.
I have a fair number of 12v 8-Amp power supplies that we ended up not using in our chargers, since we went to 12amps. I can sell these fairly cheap ($15) if anyone is interested. They are open-frame supplies, so they really must be put into a box of somekind.
Here is a link to them 12v power supply
I suppose I should post something in the for-sale group?

If you're using it for a battery charger to charge at 5amps, 4.2 wouldn't be enough. It might charge at 4amps, then again, PC part makers overrate their stuff, so it might not. It certainly doesn't seem worth the hassle to use a PC supply if it only puts out 4amps.
If you are desperately cheap, I have a very small power supply that outputs just 4amps you can have for free

find a good EPS12 server-type Power supply that puts out over 20 amps...then you'll have ZERO problems, and more capability than a rivergate Bulldog for 1/3rd the $$$.
Plus...if you need a guide...here you go!

Easy and not so easy
I took an AT style power supply (mechanical switch) and simply gatthered together some of the 12 volt wires for the positive line and some of the black ground wires for the negative and taped off the rest. I think most of the PC Power supplys that are 6 x 6x 3.5 put out about 10 amps.
