Work piece Preps:
 
   As for any cutting operation, you will need to prepare your workpiece first. You will need to mark out the outline and the position of the cut that you are about to make.

   For the circle, you can use many different tools like a round stencil or even the fan itself. I prefer to use the fan grill as the template.

   For the purpose of this guide, the "victim" will be my new Enlight EN-7237 Mid ATX case. I will be cutting the following;

• 1 X 120mm hole on the side panel,

• 1 X 92mm hole at the top, and

• removing the grill at the 80mm fan mount at the back of the case.

   If you're cutting anywhere on the case structure itself, make sure eveything that is removable IS REMOVED!! Electricity + Metal Shavings = DAMN BAD!!

   You should also vacuum the case after that ops! Like I said, I used the grill to mark out the outline of the hole with a marker. You can use a pencil but the markings tends to fade away after a while.

Safety Gears:
 
   You might also want to prepare some safety equipments for yourself. Hey! It doesn't hurt to be safe! First stop, safety glasses or goggles. Although the metal shavings would be very small, it can still get into your eyes if you're not careful. If you can afford it, get a face shield!!!

   You might want to wear gloves to protect your hands as the Dremel could get pretty hot spinning at 37,000 RPM!!! You might think that these apparels are not necessary, but prevention is sure damn better than spending some time in the hospital!!! Believe me, I have seen some pretty scary stuff in my 3 years as a Safety Officer!!
