I've bought a new case and before I install my hardware in it, I would like to make two blowholes for my radiator.
I have a dremel but I have to admit I don't have much experience with it and I don't want to mess it up because it's a new case I've seen blowholes that looked very good and were made with a dremel. But I've also seen blowholes that weren't round at all although they were supposed to be...
Any tips? Are there other tools I can use besides a dremel?

I was also thinking about making rectangular holes and using rectangular fanguards, like this one for example:

I wish I bought this. Maybe any idea where I can get things like this in many different sizes? I've seen such single screen but the size was 150 mm x 150 mm and that's to big to make a dual fanguard.
Or maybe something like this:

But without the dust filter Any idea if they sell things like these in local hardware-shops?

Use a hole saw and attach it to an electric drill is the easiest way. But the hole saw will cost you $20.

With patience, dremel will take about 30 minutes for one hole.
Practice makes perfect. Try it with an old case.

dremel sux to make nice round holes. if you have an alu case, get a circle cutter. I bought once one for RB, it cost 40€. I've heard it made very nice blowholes

@ lazyman:
Yes, I was in the store today and I was looking for a hole saw. But I only found them for wood not steel and only the sizes 111 mm and 140 mm but not 116 mm (that would be perfect).
@ TeuS:
What's a circle cutter? And what's RB?
And it's not an alu case but I can try

I don't know if it's the exact name in English , but i always make my blowholes with an electric jigsaw ( wipzaag ) with fine blades .
Just make sure you tape the top , so you don't scratch it , make al your marks , drill a hole in the big circel that will become your blowhole , put the sawblade through the hole you just drilled , and start sawing slowely folowing your lines . After that you'll just have to file and sand the edges a little , and you'r done .

@ beerke:
Yeah, I was thinking of that too. It could work because a hole of 116 mm is pretty large so maybe it's easier to make a circle with a "wipzaag"
@ jmke:
Thanks! I forgot that Google is my friend

Google sais it means RichBastard

I'll go to some shops tomorrow and check out what hey have. Thanks for the help!

go to Delva. on the first floor, ask for the circle cutters. you need the 40€ one that needs to be mounted on a drill press
