How much space do you have. Some people put some fans on top of the AVR to help pull the hot air out. My cabinet is open in the back so I have a fan on top of my AVR and it's a lot cooler now
You could buy a fan like this: http://www.coolerguys.com/840556088417.html
Coolerguys 120x120x25mm USB Fan with Grill
and then plug it into an USB outlet, or a USB wall adapter.
Or a complete kit http://www.coolerguys.com/comcool.html

That looks like something I could use. I like the complete kit.
My cabinet is connected to a wall. Would I have to make some type of vent inside the cabinet? If I do what would be the best way to do this?
Heres a pic of my cabinet.

Correct me if I'm wrong - that looks like a very closed cabinet when the doors are closed. You need air flowing in from somewhere in front of or behind that cabinet. At the very least open those doors while the AVR is on.
yes, if it is closed, you really need a way for the air to circulate out. You have plenty of room around the AVR, but the problem is there is no where for the hot air to escape. If ou have a vent, then you can also have a fan to pull the hot air out.

A few ideas:
1st, look at my 1st post in the short " Need a good recommendation on a cooling fan (Onkyo 805)" thread: http://www.avsforum.com/avs-vb/showthread.php?t=1163221
2nd, given the pic in your post#3 in this thread, I can see you using this 120x120x25mm fan in at least a couple of different ways:
a) Plot it on top of the AVR and run it at somewhat higher DC voltage (I've used mine (open air (not a closed cabinet like you use)) at 3V (inaudible) but mainly 4.5V (mildly audible when nothing else is "on", but still inaudible when music or a movie is playing). I'd think that in a closed cabinet you could run it at 6V or 7.5V and still have it be inaudible.
That's the easy first choice.
b) Cut a hole in the back of the closed cabinet, and make sure that the outside back of the cabinet is at least an inch away from the wall. Screw or bolt the fan to the back of the cabinet (*inside* close to the AVR) just above the AVR, and again run it at somewhat higher voltage, say 7.5V or 9V or even 12V.
Cheers

There is no back to the cabinet. The back is just drywall with all the cables coming out of it.
Would it be a good idea to cut a hole on the side of the cabinet? If I do that would the fan be better attached to the cabinet or on top of the avr?
Also what about cutting a hole on top of the cabinet and putting some type of vent so air could escape?

Jeez! Do NOT cut any holes to start with!!
Start with my past post 1st choice: namely just plop the Scythe sff212f fan (12v) on the AVR's hottest top spot (or even tape it down there using 3M blue masking tape (a painting tape and the least likely masking tape to leave any residue when removed (even after having been on for a long time))).
With regard to your other (above) questions on cutting holes in your cabinet, *you* are the one best person to figure that out. Wait and see if you really need to do that.
In other words, you'll 1st see if you do or don't have to do it.
If you do, you're the one who'll have the best insight on how to use the fan if you really need to cut holes in the cabinet.

Why do people worry so much about cooling their AVR? Do people have data that the AVR is being damaged by too much heat? Just being careful? Paranoid?
Seems to be common concern.
I am not yet convinced that manufacturers are making AVRs that are dangerously overheating and have shorter lifespans.
I don't know for a fact though. It would be hard to know one way or another I guess.
