ok i have one of the chieftec cases with the window and i am looking to make a side blowhole(80 or 92mm) and a top blowhole (80mm)

my questions is is how can i make a good hole on the top through the steel without screwing it up?
i know that i can use a hole saw bit for my drill on the side with an 80mm but not sure about a 92mm. but will a hole saw bit work on the steel top? (i really dont want to use the dremmel and manually do it but i can if i have to as im pretty good at it but am just lazy LOL)

As Jesse James from Monster Garage says, "We can do it the eazy way and have something crappy or do it the hard way and have something we can be proud of" My advise to you Is make a circle on a thin pice of wood and use it as a template, then once you have it cut out you can cut the holes out pretty easy with a dremmel. If you use a saw of some kind It would work but the cut woudent be as nice and once you sanded it down nice, itd be biger then what you wanted anywas

Im gonna be doing the same thing soon (top blowhole), and I was gonna use a 80mm hole saw bit, although my case is aluminium so it might be differernt.

I was gonna try and like douse the bit in water to stop sparks, friction marks, etc, but I dont know yet try to find some moddin sites, and work from that

lol i JUST finished cutting and installing mine. i dont have any fancy gear so i just used a screw bit and ghetto cut it out (after penciling it on my case) then i used a stone bit to round it out, now it looks great (cept a slight scratch, nothin touch up cant help! )

do they make like a carbide hole saw? maybe that would work good on steel.

are you sure your case IS steel? and not alluminum?

its one of the heavy chieftec cases (alienware knockoff) so yeah

when you cut alluminum, make sure to use a little rubbing alcohol, and that will keep it cool, it won't discolor or anything, and it will keep sparks down too

http://www.chieftecusa.com/dragon.htm# here is the case that i have, it says steel or alluminum but mine is very heavy and it doesnt look like aluminum.

The sparks are half the fun of cutting metal

lol....not only that, i could care less about how many sparks there are.

but i still will uise somethin to keep it from turnin colors like frictionboy said.

ya a blow hole is a good i dea, i think ill make one for me, nothing better to do.

Tape the whole top panel then mark where you want the hole. Sart the hole with your hole saw making sure to go sloooowwwww and use an oil 3in1 or even motor oil on the cutting edge and your cut will be smooth and you wont have any discoloration. A good holesaw really does help.

hey i have the exact same case and mine is alluminum... is yours "heavy" with everything in it? or empty?

well with everything in it it weighs maybe a little over 60lbs. and theres nostress oncase but im worried about the plastic feet breaking off, i also have a 2nd monitor on top of it that ill have to move for the blowhole.....ill take a pic when i get home, im at school on a laptop in pc class.

ill ask my dad to look at it too as he works with steel coils everyday, he would know.

lol i swear everyone ive seen post lately about blowholes has a 2nd monitor up top. why is that? no desk space? (go LCD!)
