Hey guys. I'm really new to rack mounting equipment, and I'm in the market for getting a rack case with at least 4 spaces. I'll need it to hold my GBE 600, a Sansamp RBI, some sort of tuner, and possibly other things. I cant for the life of me find out where to purchase a rack case or how to know what size I'll need. Everybody seems to have a rack setup yet I cant find one for myself. Also any advice on what kind of tuner to get would be appreciated, and what exactly is the function of a power conditioner? I see alot of those but dont exactly know what they do or if they are essential. Thanks guys.
