Built the rack, finally.  Now I can buy more audio stuff, just what I've always needed  
 
I didn't spend too much time leveling yet, just enough to be fairly close.  I'm not going to bother migrating everything over until I get a new surge protector/battery backup unit from APC.   
And I'm planning on switching to XLR from RCA. 
 
The surge unit pictured is just for the alarm clock and an external drive, I've got a Furman unit behind the computer. 
 
My dad took the tape measure back, but I believe its around 20" in between the bolts, and the bolts are 2" in from the front and sides.  I'm pretty pleased with it, and I think its technically my first "DIY" anything.  It feels like it will last forever, and so much cheaper than buying a finished rack.
