Advice Needed On A Case Modification

i didnt search...but i think this is gonna be a fairly unique question..

My Raidmax Saggita II case has place for 3 fans one front intake 1 side exaust and 1 rear exaust i replaced the stock rear and front fan with a couple silverstone fm121's and am replacing the side exaust with a thermaltake... anyways the front intake seems to be pretty worthless and just makes a lot of noise so i was thinking of taking it off installing a dust filter. heres my problem...

i want to cut a hole in the top of my case and install the front silverstone there...this case does not have a removable tray and i am not really motivated enough to take everything out of the case to do the modification.

I need a little bit of advice on what you guys think the best and least risky method of cutting my proposed hole.

Thanks in advance

 

Don't know how to cut it but just saying that I have seen people do this mod.

 

You really need to take everything out of the case before cutting any holes. You dont want plastic and metal filings all over your hardware.

 

LOL kiwi...yah not so much the route i was wanting to take...i was thinking more like some tin snips or sumthin...but thought that would take forever...

Edit:
BTW: searched the forum and found nothing....a google search left me sadly dissappointed as everwhere says u need to take everything out of the case....

 

As a professional steel fabricator, I can tell you that tin snips are terrible for cutting an internal radius. Not saying it cant be done though. Goodluck.
