Here we go then, my first go with the dremel and first mod in general.
Just to recap, my initial problem was that I wanted to fit 8 hard drives into the Cosmos (which has only 6 hard drive bays) and I wanted to improve the cooling.
I decided to get a
Lian Li EX-33A internal HDD bay converter. The idea behind this purchase was that I'd use the top 3 bays of the converter to place my 2 x 15,000 rpm Cheetah hard drives (the hottest running out of the 8), and leave the bottom one free for air flow. I purposely chose the 3in3 converter over the 4in3 converter for better air flow.
I also wanted to have a fan at the front of the case which would draw in cool air to actively cool the cheetahs as well as help draw up air through the Cosmos's hard drive bay area, similar how smoke gets sucked out of a car window when you're having a fag while driving

I put the module upside down in the clamp and masking taped the areas I wanted to keep:
