If I was going to keep it at my shop that would be perfect. Problem is we are moving them to our data enter so I need them to look presentable. We own an IBM Business Partner and are the only BPIC in houston so I need it to blend in 
While browsing the web, I have stumbled upon something called "rack rails that allow you to install non-rack devices in rack cabinets". They are basically a piece of metal with a lot of holes, and the idea is that you screw them together with your equipement and mount into rack cabinet.
Or if you wold like to do it differently, I think buying the cheapest used 4U rack server, then ripping everything out and putting ants inside may be the way to go.
Preferably something that looks like the server on the bottom of that picture, as it has this nice mesh that will hide whatever is inside and provide airflow at the same time:
