EDIT: Nice rig by the way, ira-k.
Thanks..I always cut my TEC tails off to about a inch long and solder on a tail of 12-14 gauge for up to a 320W TEC and for a 437W 10-12 gauge, both would be with multi-strand copper wire. Then on those tails I solder on some ring terminals, same with the wires from my PSU, that way I can bolt them together at different angles if need be. Always use heat shrink or black tape on that of course.
You know I really don't know for sure, I'd guess around $30-40 a month on electric. That's just a guestimate, may be a little higher or lower just depending on your rates, our rates here are robbery..
What chip are you wanting to TEC? The i7 is really running to hot for even the 437W, the 437W you need a special CPU block to even use it.fstfrddy makes mine, he's a member here.
I was really dissapointed about the heat out-put on the i7, the E8### chips were perfect for the 437W TEC, I was getting decent temp's with a decent OC on one. Even single stage phase is pretty anemic on the i7 from what I've heard.

...It's absolutely one of the best things for a new guy to look over, don't let it sweat you, a lot of the info will make more sense later on, and a lot of it you might never even need to use, but its a great resource.
I'd really think long and hard about investing much in a TEC loop right now, I'd wait and see how much hotter newer cores then the i7 will be running,if you already have a maxed out WC'ing rig its not much expense to go with TEC, and it's a lot of fun. But to buy all new gear for one I would be real hesitent to do so.
Take a look in the sticikies here for a mobo proofing guide Omar was kind enough to put together, a TEC sweats and condenses water a lot more then DICE/Ln2 and phase will, it's because of the wild temp swings, I'll go from -30C at idle to 6C over and over all day long depending on my load.
Honestly if was just starting out and having to buy everything I'd look at a good phase rig, or just run on water and bench on DICE or Ln2 if you can find it in your area. A decent DICE pot can be had for around a $100 and less if you make your own. Of course you don't ever want to DICE anything your afraid of killing, I'm a little heavy handed on the voltages and generally kill a chip or mobo or ram almost on every benching session. I'm a noob at it so that probably has a lot to do with it. I've only done about 10 all night DICE runs so far. I'll be doing more when Winter rolls around again, Summer is for fishing..
