The cabinet was ordered from a CNC factory.  I can't remember the name of the company, but they used to build "ready-to-go" cabinets in which you add your monitor, controls, computer, marquee, speakers, etc.  Anyway, the thing is made of 3/4" MDF and covered with black laminate.  Very good solid quality.  We routed and installed the T-molding ourselves which came out very good.  I will see if I can find any old receipts for the cabinet itself...i am thinking he paid around $400 - 500 plus freight to get it here.
