Thanks for the advice, though I don't quite understand entirely how it makes any difference how close the junction of the two PS leads and the pelt lead are to the pelt, given the fact that the resistance of the leads shouldn't be much at all. But I'll try it.
If I can get a hold of a multimeter (I really should!) I'll check the current through each PSU. I'll be borrowing my dad's workshop for a few days, so I'm not terribly worried if I blow the PSUs or do anything else that doesn't result in me electrocuting myself. At worst I'm out about $20, or a few drinks at the bar. Or both.
If I check the voltages and find one PSU is giving me more than another, I should be able to correct it by inserting an appropriately sized resistor, correct? And how large a discreprency would you worry about? One volt? Half a volt?
Would it be foolish to try to wire a 120mm case fan parallel to the pelt? It would only draw off half an amp or so.
Also with the PSU, to get an ATX running without a mobo I need a resistor (10 Ohms? Higher?) on the 5V line and a short on the 5V standby, correct? I remember seeing the exact instructions somewhere but I can't seem to remember them, and don't want to try anything until I'm sure.
Finally, putting the more powerful pump on the hotside is a very good idea, but it's not feasible right now since I know I'll have most of the equipment in a wooden box nearly 3 feet below the CPU, and I really think my cheaper pump doesn't have the strength to get the water up there. I'll try to switch them out just to see, though.
And bigben2k, maybe
you can find a better deal, but a 30A 12V supply for $16 plus shipping and a few minutes of wire splicing seems about the best
I can hope for.
I'll be buying everything online tomorrow, and I'm estimating a total cost of $130 plus shipping. I may pick up a disposable camera for pics in case I might want to write about it later. It's surely not an original idea, but with the case mods I'm planning and the classy wooden chest I'm fitting most of the equipment in, I think it will look nice enough to warrant some pictures.
And on a personal note, I'm bumming off my family's computer while mine sits on the workbench, and I just now realized the right shift key and menu button on the keyboard of this computer seemed to be glued together.
Ew.
