Hi there!

First post here - so, hello world!

I’m going to start rebuilding some old systems from my more youthful days soon. AT cases seem to be a hard find. Will I be able to fit an AT motherboard into a modern ATX case? I think I read somewhere the motherboard mounting holes lines line up the case but I will need to leave the rear I/O port plate off in order to access the keyboard connector.

Is there a known case that works out well?

Do folks just 3D print or build out custom case solutions?

Thanks!

As drive bays vanish this is becoming more difficult--getting to the point you're going to be looking for new old stock or a used case even for ATX.

Two cases I've done this with are the Thermaltake V3 and Cooler Master Elite 350. Both are long-discontinued. The latter has a ridge to the right side of the motherboard that limits how wide a board that can fit into the case.

In addition to the I/O shield the other issue is the power switch. If you use an ATX power supply with an adapter, it's possible to replace the intermittent power switch in the case with a latching one. Or, you can forego the switch and just use the one on the back of the power supply.

Basically you still can put an old AT board into the newest ATX case. Putting up drives is also less needed if you want to walk the CF route 😀

How well something like SilverStone Grandia GD09 would work for this purpose? I was considering it some time ago.

One problem I see is that there is no room for both optical drive and floppy drive.

One minor issue that you may encounter is ATX cases have 7 slots while AT cases have 8. So you won't be able to fully populate a motherboard with 8 slots unless you install a card with no ports in the last slot and remove the bracket.

Chenbro SR209 is a nice old school ATX case that is still available new.

I need help figuring out a 3d print for putting a gotek in the atx shield and a slim cd. But otherwise it seems okay

ATX I/O shield models for 3D printing

Gotek in the I/O shield? With AT motherboard Need some 3D modeling help.

the GD07 has four 5 1/4" bays 😉

Yeah, but it is much bigger and costs almost double.

I haven't really kept up with the modern world. Why do they put the PSU at the bottom now?

If talking about mine, it’s movable
