I didn't start the thread with the intention of having it move to something rack-only. It's just easier to find rack components than other empty boxes. Also, my stereo gear is larger than the dimensions you mentioned. Can't remember exactly how big right now, but bigger nonetheless.

The link I posted to thlaudio has some nice cases. Various sizes. Read my thread about extruded aluminum in OT as well. I'm going to end up making my own box from scratch using aluminum channels (different than the one linked in the thread I just mentioned - MUCH cooler )

Also, the Valleman stuff I linked is not for rack mounting and is also available in a few sizes. You should be able to get something from them easily, considering they're not too far (Belgium). There are a few places in Germany that make cases as well (one is http://www.thel.de). Pictures of one of their cases from the PJRC gallery
