I need to 'adapt' the fan holes on my next Antec case victi..mod to 92mm holes.
And was wondering whether I should use a jigsaw, or the normal dremel thing?

Which has worked better for you?
Let me know?
Thanks.

You could always use a hole saw for a nice clean cut. You'd have to clamp a piece of something (thin plywood? Maybe even cardboard?) to the back in order to get the pilot hole. But it'd be quick and take almost no edge cleanup.

It's tough to do round holes with a Dremel, and it requires a good amount of cleanup. IMO a jigsaw would be the better of the two, if you don't want to use a hole saw.

Dremel hands down, but given the option a hole saw is better

FF is right--you can't really beat holesaw for this kind of job.

Looks to be time for a trip to the hardware store for a 92mm hole saw.

That's for a drill, right?

For a drill ya, but you also want to get the center bit for it so you can drill with a pilot hole like was suggested.Or else your gunna be makin nice big circles all over your case or plexi , whatever it is your cutting, Im doing the same this weekend.

I can't just put a pilot hole down with a smaller bit, or a reamer?

Yeah but if you have a friend with a drill press now is a good time to call in a favor. I use my grandpas drill press and it makes things ALOT easier.

I would dremel it and not cut around the hole but into it from the middle. Makes for almost no edge cleanup if ya do it right. Just mark where you need to cut, then make 500000 little slits into it with the dremel and you have your cut. I reccomend useing reinforced blades for this as the little ones die fast. Thats how I do most of my dremeling, leaves clean edges.

You're kidding, right??

What a waste of time and discs...it would be easier to cut with nippers and clean up the edge.

I recommend jig for large cuts, and dremels only for small/detail work.

Click on the banner in my sig...using a jig, I cut both windows is less than 5 minutes. Edges are clean for the most part; I used the dremel with the cutting disc on it's flat side to grind out the burrs, then finished it off with sandpaper.

Waste? I used 1/2 of a reinforced disk to cut an 80 mm hole.

It's funny you mention this, because I just cut a bunch of holes last night for a project I'm working on. I used a hole saw for my 80mm holes and a jigsaw for the 92mm fan. The hole saw is way, way, way easier. It took like 20 seconds to drill the hole and I didn't even need a dremel to clean the edges, just a round file. I didn't use anything besides the drill and the material, and it looked fine (I cut through steel, plastic and acrylic). I would suggest drilling the pilot hole before you go at it with the hole saw. There is a drill on the saw, but it's hard to see around the shroud and pre-drilling the pilot allows you to do it more quickly. Also, as was said before, a drill press makes this job a snap, but I did it with a plain old drill.

ive used a hole saw once and it was bliss, i wish i had them in 80mm and 120mm sizes. they are definitely your best option, and a drill press makes them that much better (all this has been said)

but from my experience, if you can get a hole saw, a jigsaw is MUCH better than a dremel. pimp_joose made a good point that the jigsaw is better for bigger cuts. my suggestion is to get yourself a really nice bit for cutting metal with relatively small teeth if you go for the jigsaw. the bits run around 6$ for a pack of 4. the bigger teeth you use, the rougher the edge will be.

I would most likely use a dremel myself, but I wont claim it to be the easiest route.
You should easily be able to resize all your fan holes using one reinforced disk. I've used 2 so far on my current project, and one of those met an early death under my knee...lol

A hole saw works great for cutting new holes, but using it to enlarge your existing hole may be a challenge.
You'll need to clamp or screw a piece of plywood as backing, and mark your pilot hole carefully. Normally the hole saw would make its own pilot hole in the metal, but being theres already a fan hole, you'll have to find the exact center and make your own pilot hole in the plywood backing piece.

Nippers or snips will work, but I find they cause too much warpage and distortion to be useful in most cases.

A jigsaw with a fine tooth blade would work well, but I normally only use it for longer straighter cuts like windows and so on.

[Edit] Yeah Duck, those will definitely do some hella cutting, but I'd like to sit back with a beer and watch the average person cut some fan holes with one.
I have a Dewalt with a 4" wafer wheel that works great for long straight cuts and mild curves.

Yeah!! This guy gets the idea. I tried looking for a hole saw that would fit my fans a while back and found nothing. I instead used a dremel. while we're on the subject of better tools though I would suggest oh maybe this:

Either way, I would still need to make new Screw holes, which will allow me to find the center pretty easily. I will just clamp some scrap wood to the case, for the backing. Start a predrill, bingo bango, should be slick as poo.
