I'm starting to get a good rig together and am thinking of putting a patch(with power input and speaker and di output) in the front of my rack so I don't ever have to take the back off. This will also allow me to push it against walls. I was also planning on putting a fan in to cool down the whole rig. Does anybody here do this? Any suggestions? I got this idea from a sound man. He built a bass rig like this and it was awesome. It looked much easier to set up and take down.
