Better watch using those Antec tri cool fans. I had 3 crap out in 6 months one right after the other. The bearings are not sealed good. Air gets in to the end and drags dirt in with it. Makes for a short life span.

A liquid cooled 360? That's nuts.

And another thing...
USB is 5volts @ (if you're lucky) 50milliamps.

You could have just bought an intercooler for $12 bucks, haha. Are you planning to overclock your 360?

USB to 4 Pin Molex? It can cause damage the PSU of the Xbox.

Your BEST Bet would be to get an external hardrive Power supply (Plugs into the wall) because you will be putting un-needed stress on the PSU.

Also i would put a dab of solder on them splices.

A unit load is 100mA on USB 2. 150mA on USB 3.

And you can have 5 unit loads drawn from a USB 2 port and 6 unit loads from a USB 3 port.
