Got a Dremel MultiPro Kit today, tomorrow I am going to cut a fan hole in the top of one of my cases (cheap practice case). Any suggestions on how to start the hole, or smoothing around the edges? The case has a removeable top, so I can lay it out on a flat surface. Any help would be appreciated, Thanks.

Make the circle with a pencil or pen. Then try and cut it. Along the line. Just to the inside of it, then you can file or sand it down.

I have one of those, they RAWK!

I suggest you mark the outline of you proposed hole, then drill a small hole inside of this mark, large enough for whatever bit you will be using to fit in, then cut from the inside out.

Try taping up on the outside of your marked hole with masking tape to avoid scratching the rest of the top up.


If you use the cutting wheels, they will get used very quickly. That was the first thing I had to get after getting the Dremel, more cutting wheels.

Good luck.

Well, if it's an 80mm fan, than I've got a plan for you. You take a 3" hole saw, and then use the dremel's grinding wheel to expand the hole the extra 5/8ths of an inch. That's what I did, and it worked great

Or you could use an 80mm bit (you know the hollow ones with the teeth on the outside). Then will work, but you need to file a lot down.

^^^^^^Thus the definition of a 3 inch hole saw. LOL

I am no good at conversions . I use metric a lot more then I use english. And I live in the US.

Thanks for the tips, will take them into cosideration. going to use Dremel cutting wheels to get the basic shape of the hole, then will sand it down with one of the included sanding bits. Will post back here when completed, and will also post some pictures when I finish the case.

cool man

The hole is cut, but now it needs a coat of spray paint. Gonna sand it down, and (as the rolling stones said it) paint it black. I will post pictures later on tonight on this thread, so come take a look. Probably will have it painted by sunday. I cut the hole a little too big, but the extra space arond the sides look pretty good, and it won't hurt the airflow either.

this post might come in handy, a few good tips

Took some pictures, how does it look? I bought a window kit from CompuSmart tonight, comes with red tinted plexiglass and the rubber framing (Hope I have time to install it tomorrow ). Also got a red cold cathode. Guess I'm going with a red theme. I only have regular black case fans, but when I can afford it, I will get some red led fans.

The specs on the computer I'm working on are:

Pentium 4 @ 1.3GHz (423-pin)
256MB DDR266 (gonna upgrade to 512 later)
PCChips mainbord
Antec Heatsink (Jet Cool 423-pin)
30GB Maxtor HDD
Generic case with mods

Going to run Windows 98 for a while until I can afford Windows XP

just paint your fans... remove the sticker from the backside of the fan, and under that sticker you will see a post dead center, take a small screw driver and pop out the "C" clip and the fan blades will slide off, tape off the magnets and wires, lay out the fans, and paint away.. simple yet effective ( look for that new krylon paint called "fusion" its made for plastics and leaves an awsome gloss

These guys have great fans good CFM and $11 cheap
