I have long been a fan of rack mounting components. I know that some people are concerned about vibration issues but that has not been an issue for me. My gear is mounted in a 19-inch wood rack that I had made years ago. Most gear that's not available with rack ears can be fitted to rack mount - the folks at Middle Atlantic can almost always make it work. A component can sit on a rack shelf when that isn't practical.
Rack mounting prevents a lot of damage because components can't move. My cabling has just enough slack that I can roll the rack out from the wall and work from behind it as easily as from the front. That's a terrific convenience.
