The 4 - 2.5" 's will be in a rackmount which will require a molex connector to power all 4 drives and I want to put a fan controller in which will require another molex. Other than that, the video and audio will be onboard, and i will have a spare PCI-E ethernet card, and a small handheld touchscreen monitor.

The highest rated PSU for mini itx i can find is 120w, which i dont think would power the 4 drives much less a quad core. Im thinking im going to need around 300w, or at least thats what Thermaltakes watt calculator told me. Maybe i can use an external power brick or something? I'd really like to keep everything internal though. Please help, google is not being my friend today.

Welcome to the forums!

According to my calculations you need a PSU with 13 amps on the 12v rails.
It's your processor that is using the most amps. If you can find a more energy efficient one, you might be able to use a 120W power supply.

I think you're pushing the bounds of what you can actually do with ITX.

mini-box.com makes a 150W PSU - currently out of stock, but they say they'll have more 4/6/09. Its 24 pin, though. I assume somebody makes a 24->20 converter.
