Cooler suggestions for horizontal mounting

[EndersShadow]

So I have a somewhat unique need. I have a couple pieces of Home Theater gear (HT Reciever, 5 channel amp, sub amp) I want to throw some large low rpm case fans on top of to help keep them cool. They are all currently enclosed in a entertaiment center that has doors on the front, and louvers on the bottom and the shelves to help with convection. I did NOT install the back piece so they can exhaust air out no problem, but I want to aid them in that. All the pieces are around 19" wide x 19" deep so I can use a large 200+ mm fan to keep them cool.

What I dont know and need help with is figuring out what fan type (ball bearing, fluid dynamic, etc) would work best in this application. I will have the fans mounted horizontally on top the pieces of equipment.

Again I dont need something with a lot of rpm's or even something that has a high cfm rating, just need something to help draw air out and be somewhat inaudible, and preferably it would be black.

I also need suggestions on what to buy so I can plug them in. I know I could buy this adapter but was wondering if somethign else out there was better/cheaper, etc. I would then also also buy this or this so I didn't have a bunch of molex connectors piggybacking off the one molex output, and I could keep the fans mounted closer to where they needed to go.

Any suggestions appreciated.

PS I looked at Notebook coolers, but the problem is most of them are a bit too tall for my use where they either wont fit where I need them, or are more expensive or have too many things I dont want (like LED's).

I have used both Corsair and Thermaltake 200mm fans and both work long and quiet when mounted vertical. Neither one works more than 6 months when mounted horizontally! I had contacted Noctua within the last few weeks and they plan to have a 200mm fan available in early 2015 but that doesn't help you now. Any one of the Coolerguys power units would work well for you, I would choose which ever combo gives you the neatest install.
How about installing the back piece and put a vertically mounted single fan in the top.

Maybe look into the replacement fans for the Antec 900 case.

I'd have to chop it up way to much to make it work. I have a bunch of cables routed through there and the install is neat and clean. It would likely suffocate my amp and my AVR (which already has blown 3 HDMI boards)...

Here is kinda what I am working with right now.

This pic does not show the 78 lbs amp that is in the middle section. It was easier to install the amp once I move the rack back a bit. But the middle section has 5 sets of speaker wire and 5 interconnects going to an amp that takes up the whole middle section. If I put the back on, I'd starve the amp and AVR for exhaust and likely blow them both. On top of my AVR there are 2 120mm Antec fans from my P182 currently ghetto wired off a USB cable which hooks into a 2 prong to USB charger. I was hoping for a cleaner quieter install there, and then on top of my 5 channe amp, and the sub amp (also not pictured) that is below the AVR.
