i want to put a 120mm fan in the back of my case but there isn't a flat space large enough. what i mean is that the space is there but half of indents so that they aren't flush. what can i do to put a 120mm fan in that space?
but then the bottom and top won't match up. imagine you are looking at this from the top

so the fan half the fan would be sticking outside of the case and the other half would be flush with it.
would be as effective to just drill holes threw the metal in front of the fan. and the there would just be a 1/3 inch gap on the side between the fan and the metal?
i guess i could just put some cardboard on the sides that wouldn't be flush.
but i really wanted to cut a big hole to get as much air flow as possible.
You could do something similar to what I did with a case like that. It was a supermicro case, only had room in the back plate for a measely 60mm fan. Soooo...out came the dremel and I cut that entire plate out. Then took the cover off a Compaq EN 6000 (old P233mmx) and cut out a new back plate. got out the blow torch and heated it up to help shape it. A little more dremeling and shaping, lined it up, mounted it on the case where I cut the old one out. I ended up mounting the 92mm fan from the Compaq Powersupply (Papst fan it was) on there. Took about 1 full day to do (prolly would have taken a half a day if I didn't screw the first replacement backplate up).
I'll post pics of it in a bit. It's not the *best* looking job...but it's functional, retains the cases original rigidness, and moves a hella lot of air (with a matched 92mm modded to the front of the case...both controlled by a rheostat).
here are pics. no flames please...it was my first case mod...and was really in the interest of cooling my new P4 I had in there (which is now in a nice Antec case).
Ignore the fingerprints and dust...It's now become my 5 year old's computer
