Well to the subject of racks...   i looked and seriously though about mid-atlantic , etc...  Even had the wife's approval despite the price.   But shelves or custom face plates for rack mounts / ears, etc would have been outragous...    I decided to build my own.  3/4" ply (good stuff from the wood place, not HD/Lowes).  I butt joined (glued & pin nailed) some thin strips of red oak i had left over from my stair project to the front edges of the shelves and sanded flush for edge treatment - blind dadoes up front (recessed a little so the door could be near flush with the trim and have room to pivot).  Coated in black enamel semi gloss ...   I cut out a stud, moved it over and built this into the wall (a little over 19" wide).  Screwed to makeshift header/footer and studs on each side.   It's not going anywhere... 
For cooling, my father in law picked up a fan usually used to aid in air distribution in ductwork.   I haven't hooked it up, but will run off a relay connected to an elk output and triggered by a rack mounted temp sensor rules...  (temp sensor will be near te top near my Onkyo and STBs which product a ton of heat)
All in all, paint/glass/wood was under 200 bucks and the WAF is very high...
I need some black plastic wire wrap.  Unfortunately my monnster speaker wire and long runs of composite video cable are white.  and as you can see sticks out a little from behind - esp. when the door is opened
