The purists among us felt that the stock power supply was a bit noisier then it might be - you might never even hear it... Take a look at The Socket which is a battery power supply. No point in being too picky since there is nothing else like Opticis out there. If you don't want to bother just get the premium Belden gold USB cable.
The choice between an external and an internal drive will make no difference. You need to understand that there is a new paradigm here - this is truly digital. Computers push data in and out all day long - its what they do 24/7/365 around the world. The amount of data involved and the speed of data transfer required to make perfect audio is absolutely trivial. Consider that on my rig I can in digitze a CD (rip) at the same time as I am playing back two different songs - one via USB and one via Ethernet... and surf the web...
If you stress your computer by asking it to do a lot of other things at the same time - particularly data intensive things like process large photoshop files, you may get it to hiccup now and again. You will hear it, it will be momentary and music will resume automatically. You will then have the choice of turning off the music or stopping/reducing your other activities.
There are very few things that will impact the quality of computer served audio. First and foremost is how the data is ripped and compressed. Apple Lossless with error correction "on" and all choices under Preferences/Playback "off" is all you need to do. Second is of course how you get the audio data off the disk and back into music. The Brick is as good as they come, perhaps a bit better with Opticis particularly if you live in a RF/EMI noisy environment or have ground loops. End case.
As far as display, I run iTunes on my computer display. Take a look at the new Apple TV product - it may solve your problem.
