will it make a good 486 gaming rig?

Technically it would be a very bad 486 gaming rig, because it's not a 486. Those were Pentium systems... they came in 90, 120 and 150mhz versions I believe.

If I saw one for $20 or less I'd probably pick it up just to play with, but realistically there's nothing in particular to recommend it as a gaming system, at least not compared to an average consumer-class machine of the same era. The EISA is an interesting feature, but it's more of a curiosity than any practical use, and the fact that it only has two PCI slots is troublesome for upgrades (and one would pretty much have to be occupied by a graphics card, since the onboard VGA is pretty weak).

I meant to write Pentium, sorry 😀
Wrote that at 1AM.

I see, well, this system seems to be a card type CPU. Ive asked for more pictures to confirm that. Usually people rip out the original and insert some Pentium III inside the housing or something.

The CPU board looks like this. It's not really a card-type CPU, it's just a regular Socket 5 CPU that happens to be mounted on a daughterboard. A lot of the Compaq servers were set up like that.

Awww, but its cool none the less 😁
Still waiting for info.
