Anybody know where I could buy a good 3" or 3-1/8" Hole Saw & Arbor set to cut a hole for an 80mm fan on my side panel? I seen a lot on ebay in a kit but I don't think any of them cut metal/steel/watever my side panel is made of 🙁

Go to your local hardware store. You should be able to find them for ~10 bucks. That is about what we sell them for at Ace Hardware (where I work), and we tend to be a little more expensive than a "big box" store like home depot.
 
Ehh I bet there's plenty of stores that sell them but problem is I'm stuck in dorms with no car and there's NOTHING within walking distance. And all the people with car's I know go home on weekends and leave me stranded 🙁
 
I buy all of my hole saws at my local Sears Hardware; they carry the Mailwaukee hole saws which are nice. Only caveat with the Milwaukees is that you need a 1/2" drill because the arbor is pretty big. I have found 60mm, 80mm, and 92mm saws there (other sizes too, obviously).

You can find a bi-metal hole saw Home Depot, Lowes, OSH, etc. The size you're looking for should run $10-$14. You should also be able to find what you need at your local Aubochon's, Tru-Value, etc. but it may run you a couple of bucks more.
 
"bimetal holesaw" is what you want.

you know what i did for my first holes?

they were for 120mm fans. i bought a 2.5" holesaw, and made a clover, 4 circles offset. a year or 2 later, i finished it off, and cut off some odds and ends from the clover with a jig saw.

if you have any questions after getting the holesaw, come back and ask.

here is what you shoudl get:

  • holesaw
  • arbor (the drill thing for the holesaw)
  • cutting lubricant (ask a KNOWLEDGEABLE sales person, it's most often a light weight oil)
  • protective eye wear (fully closed googles recommended, not just safety glasses)
  • protective gloves, you dont want to get cut
  • a sanding block or sand paper, to polish the edge so you dont cut yourself
  • a piece of wood to drill into you can practice on the wood,, and use it as a backing for the panel when you drill so you dont bend the cover
  • if you drill parts of the case, make sure it's empty, and you clean off all metal shavings, ALL. vacuum, and wipe it down with a tack cloth.
 
If you don't want to invest a fortune to cut a hole or two, buy a nice jigsaw and some good metal cutting blades. Don't forget to cover the area with masking tape to avoid scratching it with the bottom of the saw.

* Skil Jigsaw
* DeWalt Blades (The 3" 32 TPI blades work very well for me)
* Scotch masking tape (2" wide should work just fine)
 
The ones I saw at my local B&B Hardware (big enough for an 80mm fan at least) were ~40-50 dollars. They looked pretty flimsy, too. Haven't been to Home Depot recently, but I figured it would be about the same price from the big chain store. Maybe I'm wrong.
 
You get what you pay for......Mine cost about $35 at sears with the arbor. It'll fit in a 3/8 drill motor. The thin steel or aluminum in these cases is easily cut. Be sure to drill a pilot hole (small starter hole) that is smaller than the arbor bit. This keeps the hole saw from walking(Moving around). Use duct tape to insure a clean cut. A high-speed drill motor also makes a cleaner cut.
