There were two main things I wanted out of this project:
First, I wanted to use Thunderbolt as my drive interface, so that I'd never experience any performance bottlenecks as a result of my connection, and also because I wanted a forward-looking technology (rather than Firewire, which is clearly on the way out). I already had some SATA drives on hand, so I decided to get LaCie's eSATA Hub
. At $200, this was the priciest part of the project by far. But as I've said, I was going for speed. A pair of SATA to eSATA cables ensured I was able to connect my drives to the hub.
My second goal was to make the resultant device as "authentic" to the original as possible. I wanted the LCD, the lights, and the buttons to all work. I decided that: a) the buttons would control iTunes and the volume, b) an LCD would display the current track, and c) the status lights would be replaced with a music-responsive, colour LED lightshow.
I decided to keep the original RaQ power supply in order to power my drives (with the help of some molex to SATA power adapters). Everything else was stripped out.
