I have a few questions on this OPUS product:

First, do you think this will be able to power a USB hub and my external sound card (audigy NX), I'm guessing it will be fine, but I want to make sure.

Second, is there a premade case for this or will I have to build my own?

Third, will I have to solder the 5v wire to the circuit board, or do the wires already exist?
