If you wanna do it at home, then u'll need some basic tools like Ruler, Filer, small saw, hand held drill machine etc. But if u've got a costly case then have it modded by professionals only.
I have a cheap Cabby (and I am too lazy to go and buy all the tools :bleh: ) hence, I mod my Cabby with whatever I get in the house. All I needed was some old kitchen knife (with jagged edge), big and small filers and a pen knife toolkit (just like a Swiss Knife). I have used the kitchen knife to cut small parts of my steel case and some plastic parts too... Then I do the filling with the filer to smoothen and shape the cuts...
Here are some photos of what I did yesterday...

My two 320 GB HDDs were very hot at 54 degree each, so I wanted to fit a
HDD cooler I had brought earlier. But that did not fit in the 5.25" bay (coz the HDDs were on a
anti-vibration stabilizer). The only thing I could do was cut the front covers of the 5.25" bays and fit a spare 80mm fan there...
So out came my trusted jagged-edged kitchen knife and after some careful measurements, cutting and filling, I got the fan attached. The HDDs cooled to 45 degrees with the fan filter on and without the filter it cooled till 41 degrees. Now I am planning to put some heatsinks on the HDDs to help dissipate more heat off...
Also, I had modded my Cabby some time earlier. Here is the text (I had posted at some other forum)
Fitting the TrU120Ex in my Cabby was a close shave... The heatpipes were peeking out a little. So I had to mod my cabby to accomodate the Ex.
So here's how I did it...
Traced out the heatpipes location on the acrylic sheet after removing it from the side window. Then made small holes on the marked location by passing a hot screwdriver through them. Then increased the size of the hole by scraping the holes using a plain edged sharp kitchen knife
After that I cut the metal using a jagged edged kitchen knife
again
Finished it with a Metal File to make the sharp edges blunt. Then painted the filed edge with black permanent marker
Yaa, I know it is a very
crude method of modding, but I achieved the results that I desired!!! And that's what matters...
