Bissquitt,
It's a custom built rack out of 3/4 plywood and audio equipment Raxxess rails. If you want the specs I could look for them but it was made to house my APC UPS being the deepest and enough room below for cables and a less deep top shelf to help with airflow. Additionally I mounted caster wheels to roll it in and out of my office closet.
Here is my configuration along with a custom built rack.
