I wouldn't call the AT a 'looker' but it has that boxy IBM style that I love for some reason. All my classic PCs are IBMs except my P4 which is a Dell.

Well, it surely has an iconic look. I'd dare to say that AT chassis and the Model M keyboard had more relevance in late 80s than an PC or PC/XT.
If we look at manuals or literature from that era, the wider AT chassis was some sort of reference. Both XT/Turbo XT and AT clones used AT style chassis, too.

And it makes sense, I think. The IBM 5170 chassis was wider, had been better suited for housing fixed disks and large expansion cards.
It also matched the width of the Model F and Model M keyboards, so it looked cleaner.
Edit: The full size keyboard variants with extra keys, I mean. There were different models.

The downside was, though, that the IBM MDA or EGA monitor looked a bit tiny in comparison.
A slightly bigger VGA monitor or multi-sync monitor in a boxy chassis would be a more fitting companion, maybe.

Sounds like between my XT and my 486 I shouldn't have much trouble running most games (at least the ones I care about).
I'll have to look into this SETMUL program for disabling the cache, I've never heard of it before.

Well, it really depends. 🤷 If it's merely about usability, then there's no dire need for an AT.
Just like there's no need to own an original Gameboy to play old GB games.
An Gameboy Colour or Gameboy Advance SP can play them, too, even though the gaming experience is a bit different.

I was considering purchasing an IBM AT computer but my Objective was to play the Most computer games on “ONE COMPUTER”
I grew up with IBM computers and used them in Schools so I am fond of IBM computers.
But I have been looking for the Perfect All-in-One computer that plays the most games since that is my Priority.

Here is what I Decided on:

AMD k6-III+ @ 550mhz
Super socket 7 motherboard
256mb RAM
Voodoo-3-3000 AGP
Creative AWE64 sound card
3com 3c509b Network card
CF card for hard drive
52x CDROM
DVD
USB
PS/2 and Serial ports
Floppy drives ( 3.5 and 5.25 )

This setup tics all the boxes

3dfx/3D Now/MMX support

And using a Utility like SetMul ( Set Multiplier ) you can slow down the CPU as slow as a 386 CPU

So this will allow you to play a large assortment of games.

Here is what I Decided on:

No Gravis Ultrasound ? 😁

I have a P3 IBM IntelliStation Pro M that's my 'all in one' PC. I don't have it hooked up recently as I was able to reacquire my original P4 from the friend I sold it to so many years ago and that took its place but I keep it around 'just in case'.
