1. Where do I get them?

2. What's the best way to cut the hole for them?

3. Should it blow air in or suck air out?

4. Does anyone know where I can get a switch that will supply variable voltage to the fan based on temperature (not necessary but would be nice)?
 
1. Where do I get them?

Um. Hardware storemight have them. A PC shop will most definatly have them but they will likly be 12V DC vs 115V AC so a power converter will be needed. RadioShack should also have them in either or power setting.

2. What's the best way to cut the hole for them?

A holesaw bit for your drill.

3. Should it blow air in or suck air out?

I would suggest they blow cool air in and have some vent holes to allow the warm air to exit.

4. Does anyone know where I can get a switch that will supply variable voltage to the fan based on temperature (not necessary but would be nice)?

The nice ICECAP fans that you can get online have a thermo voltage regulator built in. My first guess for something DIY would be radioshack.
 
get the Vantec Stealth 92mm fans. i bought four of them for my canopy (220w PC lights) and they are dead quiet. no need to decrease their voltage at all.
