Thats good idea but not for me cus i have the space free DTV'S CCK and I LIKE IT THAT WAY...! tanks for the advice ne ways.. 
I like YOUR USE OF CAPITALS for no reason, its NOT WEIRD AT ALL. Honestly though, I appreciate the irony of a thread concerning heat, space in a cab, and cooling methods and in your picture you have 2 heat generating power supplies (arcade and PC) and a CCK that takes up a bunch of room and probably generates heat or uses an AC adapter that generates heat.
I mean hey, you get em for free and that works, but not every comment made on here is an attack, sometimes its just an observation. Even if I got those boxes for free, I'd still prefer a $20 USB wireless stick, less room, and less wiring. That's just me. There's nothing wrong with what you're doing , I am just presenting an alternative for you and others. I could also say that you could mount that on the back of the cab and run the wiring in to free up air space and increase cooling but I wouldnt want to offend you again
