I need to cut out the corners off a heatsink, so it will work with a mobile pentium 4 in an asus pundit. (there are little white nubs at the corners of the heatsink retention thingy, which raise the heatsink about a millimeter too high for the mobile chip (cos it has no heatspreader).
How would you cut through thick (half a centimeter) solid metal on a heatsink

are there people you can go to who cut metal for a fee? like key cutters or something? or would that be a waste of money.

The heatsink will either be made from 6061 type aluminum, quite easy to cut through
or a copper alloy - soft but gummy to cut.
A hacksaw will work, just a few strokes to cut through either and use a small fine file to dress & smooth the burr edges.
A Dremel Tool is a small high speed rotary motor - like a drill, that can hold a rotary file
bit -
it cuts quite fast but leaves small fine metalic chips - grain of sand size.

I actually picked a dremel rip off: the Black and Decker wizard. I've had it 6 years and it has taken some serious abuse, including cutting 6 x 9 holes through 2mm steel and only last weekend I cut the welds from a restrictor in my exhaust. Only now has it given up, and it's actualoly only the tool release mech that's broken. The motor is fine.
One 'trick' I've found that works well is when you buy one, use it for all sorts of jobs. Then throw away any partially used tools (or keep them to one side) and return the whole thing saying that loads of the tools (eg cutting disks) were missing when you opened it up. You get a brand new tool and free consumables.
I prefer the wizard over the dremel as it's slimmer and the power selector is more dynamic and smoother. Tools from the dremel and wizard are interchangable.

Probably just use a bench vise and a file if I'm just knocking off the corners. Heatsinks are soft so you could do it easily enough. If I wanted precision I'd use a milling machine.

That's no trick. That's fraud. Might as well go brag about throwing a brick through a window and taking what you want for free.
