do you want to put the hole in the front? if you can get that fan bracket out, go at it with a hack saw. or you could use a drill to make the holes bigger and just mount it in the middle. unless you are trying to make a big cutout.

to get the right size... use a CD to make the outline, perfect template for a 120mm hole.

Then use a dremel or whatever to cut it out.

For what it would cost to have it done, you are better off doing it yourself.
BTW, LilBuddy, that is the 3.5" HD bays displayed.

Because of the 4 80mm cutouts, I'd remove them, get a piece of sheet aluminum, center and cut out the 120mm hole(use a CD as template as Morbid suggests) in the aluminum, and mount the aluminum in place in the 80mm area using the corner mounting holes. Then you can mount your fan in place easily. It should work fine, and you'll have a much neater job. Remove the areas I've outlined in black.
