Baby AT motherboard in a modern case with form factor support

I'm putting together a legacy Socket 7 system (from the early 90s).

The motherboard I'm using is a Shuttle HOT-553, which I'm fairly certain is Baby AT (if someone could confirm this, that would be great).

Can I quite literally install this Socket 7 motherboard into a modern case with Baby AT support (example), throw in an AT power supply, and have it all function, even with the default power switch in the front (which I assume is an ATX switch)? It was my understanding that the ATX power switch scheme is different than that of the AT scheme.

And how about things like the I/O panel? Could I just use something like what's pictured towards the left in the following image?:

So basically, the 2 questions are:

1 - Is my motherboard Baby AT? (Shuttle HOT-553)
2 - Can a modern case with stated Baby AT support (of which there are several) also handle the power switch differences of the AT standard, or does something need to be modified?

Yes, your motherboard is Baby AT according to your link. Actually, it's a little shorter than even the official Baby AT.

The power supply and power switch are absolutely different than ATX. The power switch in an ATX computer is a momentary contact switch that signals the motherboard to signal the PSU to power on. The power switch in an AT computer is a toggle switch (usually in the push configuration) that literally has mains voltage running through it. Something like this would work fine, but you'll need to modify your case to accommodate it.

Yea, I'm well aware of those switch differences (I actually had AT member jaqie explain it to me earlier).

I just wasn't sure if, given the Baby AT support of the case, it had a dual type of switch or something. Too bad it doesn't. In any case (pun not intended), I'm rather surprised that there are cases with Baby AT support nowadays. I totally wasn't expecting it.
