All great responses but I probably should have been more clear. Most of our devices are not rack mountable. The NVR, UPS, and router are not rack mountable.
Here is the specific project. This is a take over (someone else installed it) and normally we would do a small 9U or 12U open or closed rack, with some shelves. We would replace the multiple switches with a single larger switch. The UPS would be a small personal unit.
Here there are several issues. Its right in front of the door a rack here would in the way. The attic access is directly above, so moving the rack up is not an option, and all the cables land here. We could put a patch panel in, and move everything elsewhere, but the HDMI cable for the TV's lands here as well.
Just trying to find a way to tidy it up, without rerunning a lot of cables, etc. The primary scope is adding cameras elsewhere, so we are trying to squeeze this into the project. I hate having our name on stuff like this...
