I have always found TEC based cooling very interesting but seems like every time i tried it I don't do good enough of a job and break something

Most of the time it's because didn't have the proper cooling for the hot side.
Now since I've got more hardware on hand I'd really like to try again.
Here is my check list.
3x Swiftech 3x120mm Rad
1x MCP-655 Water pump
1x Water Block for both 1366 and 775 Swiftech GTZ
2x 136.8W Peltier 40mm x 40mm (that's the smallest i can find that's got the most power)
1x Corsair 430W Power supply
I am thinking about putting those 2 TEC peltiers back to back hooking it up in series.
Having the second peltier cooling the first one and having the water block cooling the second peltier.
Now i am just wondering how should i power everything?
I am thinking about having the 24-pin or one of the 6-pin GPU cable to power them.
Really not thinking about modding or changing the physical appearance of the PSU.
One of y'all showed me a pix where the water stuff is in another box, i kinda wanna do that.

just try it out see what's up
