What I want to do is build the O2 into the front of the computer without any external wiring (just powered by my psu, and connected to an internal USB header).
The benefits for me are twofold: cleaner power for the amp, ( I get pops and crackles from power jitters in my building) and a cleaner desk.
My O2 has rear power, so it would be really easy to build it into my case.
If anyone has any tips or thoughts it would be appreciated.
It's much more work than you realize. The O2 was built to use an AC adapter. You're only going to get DC through a computer's power supply. Even if you figured out a way to bypass the rectifiers in the O2, you'd still be powering it with your computer's power supply, which is just about the worst thing you can use to power audiophile equipment. You may get more noise than before.
The AC adapter is rectified to DC within the O2, then sent through a regulator and batteries. I doubt seriously that you would be hearing pops and crackles because of your power - the O2 should be filtering them out. Just speaking from experience, the pops and crackles may be a result of your O2's builder, not the line power in your building. Or, you have it placed next to a particularly noisy environment (computer, monitor, cell phone, etc.).
