OK, I figured it was time to post some more information of why I'm wanting to go with an AV rack. First, the TV cradenza I am currently using was not designed to house the amount of weight I have in it, nor does it fit properly (I made some slight modifications). Also, my long term goal for this project is to eventually install a projector on the back wall, making an AV rack pretty much essential. And lastly, I have some major cable management issues. The current setup is very difficult to work with if I ever need to change anything. I like being able to go back there from time time and tweak things etc, and right now it's an absolute nightmare! Here's some pics. This should be pretty self explanatory:
As you can see, this is a royal pain to work with. I'm looking for something that would meet the needs I mentioned, at least 4 shelves capable of holding 60-100lbs with ease (2 shelves need to be able to safely hold 100lbs). I was also hoping to keep this under $400 if possible.
