Dumb Question, Still Need Answer Though

how would i go about making a 4 inch hole in 3/8" plywood for my fans. im not good with wood

You would need a http://www.coastaltool.com/a/lenox/holesaws.htm

What do you have to work with (cordless drill, drill bits, hole saw jigsaw)i need to know

If you have a drill with drill bits use a 4inch plate or pipe to draw the hole then carefully use the drill to make small holes around the marked 4" hole until all the way around and pop the wood out. Make sure to secure the plywood and have a piece of timber under where your drilling for the drill bit to go right thru the plywood be very careful
A hole saw would be ideal or a jigsaw

Dude I am pretty sure the site is entirely for drills and power tools. This would be an application for a cord or cordless drill. A jigsaw works but the finished result is based on your competence and steady hand.

Just go to your local hardware and ask for the necessary bits to run a 4" hole saw.

cordless drill, 4" hole saw costs like 15 bucks if that

right on, i guess il just go with the 4"hole saw and my cordless drill. can i get the hole saw at homedepot ?

yeah.
it will be with the drill bits and stuff..
be careful..

Dont worry i will, also someone PM'ed me and told me to put both fans on the same side of the box one on the bottom of the wall on the top of the same wall, apperantly it creates a circular air flow ?????

thats a lil different than the hole saw question. post it in a new thread and youll get a faster answer.
