I couldn't resist this weird little motherboard when I saw it on eBay - its a "Syntax S8601MP 1GigaPro" totally integrated mATX system with a VIA Apollo Pro 133 chipset and a soldered on VIA C3.

There's definitely a weird nostalgia in this for me - I think this was the exact board I used to build a separate desktop in a slim mATX case for my parents to use, so I could have the main PC I'd been building and upgrading for myself. Although I had a feeling the one I had was branded as PC Chips?
Basically, it is directly equivalent to a VIA EPIA 800 mini-ITX board (which I already have one of ... ) but with a few key differences that make it seem kind of cool to me: it has a floppy controller; it has a game port; and it ....

Kind of has an ISA slot?
As far as I can see, the only component missing apart from the ISA slot itself is a quite small through-hole capacitor? I'm tempted to try and find a new ISA slot connector and solder it on, but I figure I'd have to also fit the capacitor? Is there any way to work out what value and voltage it would have to be? There are hardly any photos of this board on Google, and none that I could find with the ISA slot in place! 🙁 Would looking at a similar Apollo Pro based board give a good enough guide?
Is there anything else I'd need to do in order to add the slot?
Seeing as the board has the 686B southbridge, the same as the EPIA 800, it should also have pretty reasonable SB Pro DOS emulation (there are the options to enable it in the BIOS, although I haven't got as far as testing it yet). So it could be a totally integrated DOS PC, complete with floppy and game controller ...
So I'm torn - do I set it up as a totally integrated system, put it in a beige slim mATX case (like the one I put together for my parents) and rely on the VIA audio?
Or do I add the ISA slot and use it with a 'real' ISA DOS sound card - but needing a case that has full height expansion slots?
(Or perhaps ... I even find one of the physically smaller ISA YMF or Opti sound cards that only had a half height PCB and game port on a cable, and 3D print / hack some half height brackets to accommodate it in a slim case? Or are the small PCB ISA cards like that always trash when it comes to audio quality?)
