First time modder - 2 questions

Antec P182SE Motherboard tray/ panel cutout for easy Heatsink access

I would like to create an opening in the side panel to access the heatsink backplate without completely having to remove the entire motherboard when swapping the heatsink. Many cases already have this as a stock feature, but not the P182 as you can see in this picture:

This is what the end result should look like

(note, this is NOT my case, this is an image I found from someone that has the same case and that did the same mod)


I have 2 questions:

1. Is a Dremel the correct tool for this (7.2v)?

2. Will a Sheet Metal bit work or do you think I should use a wheel accesory instead?

If anyone who has done similar projects has helpful pointers or suggestions, your feedback is greatly appreciated! Thanks in advance for your help.

I'd drill a hole at each corner of the square, use a cutting wheel to cut between the holes, and chase the burred edges with a file.

Simple and to the point. Love it! Thanks for the answer. I'll post pics when complete.

Best advice and approach IMO - good luck w/it

Yep, this is the way to go.

Personally, I don't like the battery operated Dremels, but I'm assuming you've already got one, so go with what you've got.

Also, just a tid bit of advice when using the cutting wheel. A common mistake is to cut all the way through the metal and then cut along the line. You get much better results when you first make light cuts all the the along your lines and make multiple passes. Your cutting wheels will last much longer and your finished cuts will be must straighter and cleaner.
