Anyone here tried or did mod AT case to access ATX hardware?
We can see lots of sleeper PCs, but rarely people do AT case with ATX mobo.
I tried once to do that, had to do a lot of dremel work etc but was wondering if anyone saw project like that so I could take some inspirations from.

Better stay away with your dremel from those remaining AT cases (especially if they are IBM prototypes...😉

This. AT cases are scarce now and ATX cases are like shit in a cow pasture. Don't destroy the few remaining AT cases

I disagree - I think its worth modding those cases to give them new life. If you know how to sue dremel and have modding experience, you can mod it and make it reversable.

Nope, @phinix, I definitely disagree with dremel-based modding of AT cases. If you have vintage AT cases, sell them to someone who needs them, and don't cut them up. There are brand new cases with a vintage look, if you want to buy them.

I have to agree with the others here... it took me a couple years to find a couple good condition AT cases to build actual AT systems in and it makes me happy to finally have a couple. I wouldn't hack one up for an ATX build when there's an abundance of old ATX cases - many old ATX cases have fun and wacky aesthetics since they were manufactured over various periods in PC history. Translucent blue, funky plastic waves and ripples, oddly shaped buttons, 5.25" bay drive covers, early cooling solutions, etc. I think it's totally possible to make an old school looking build in an ATX case.

Of course it's totally OP's choice to do what they wish with their belongings, and micro ATX in a baby AT case *would* be cool, but I'd rather see a tidy AT build in it instead. ; )

How exactly do you imagine it? ATX boards I/o section is significantly bigger than a typical DIN keyboard hole.
You can also see from the vibes that you are pissing people off with those notions

Many years ago I hacked up a small AT case to fit what was called a "flex atx" Gateway branded socket 370 motherboard for a friend.

I think it was a Coppermine P3 and I think had onboard video, can't remember much else.
