Look what I made. It's a fully floating, 2RU rack case. It may be hard to tell on the pic, put it's made from 12mm plywood, seperated by 20mm of packing foam. My amp vents to the sides and doesn't have an internal fan, so I incorporated a couple of 80mm fans the run of 12v power. There's a power board with 4 power points hidden at the back. So far I'm only using 2 (the amp and the 12v adapter for the fans). Front and rear lids are completely removable (none of this trap door bullsheet) and the handle is one of those Ernie Ball heavy duty ones that drill right through the wood and anchor to the other side. Both lids and rack are covered in carpet left over from my home made speaker cabs. What would I do different. Well it's heavy. 14kg. I might use thinner wood for the inside layer to trim some weight. The fans work brilliantly.
