Bought the kit from Autocostruire (the AudioDigit).
Very nice unit, easy to configure with a nice sound.:D
Only prob is the single input as standard plus the volume pot that comes with it gives quite a lot of noise when moved.:(

Here's some pics:

astonishing craftsmanship

Yes, I suppose so. Steel can be tough to work, especially if you don't have the tools. Aluminum is a lot softer. Consider a small drill press stand - they're really not that expensive, and can help a lot.



A Dremel tool can cut just about any shape hole with acceptable results, although it may take patience and a steady hand. For rectangular holes, drill a small pilot hole in each corner (with the drill in the press stand) and used the Dremel to "connect-the-dots".



Are there any photos of the inside? I'd be curious to see the circuit board / wiring / whatever....
