I found a (new?) AMI Enterprise IV motherboard, with all the manuals & accessories. Apparently made in 1995 😀 It has EISA slots and VLB slots, with an integrated IDE/Floppy/serial/parallel adapter, cache and apparently PS/2 mouse support? If this one works, I think it's the right system to use with the Intel DX4 Overdrive 100 I got hold of:

It looks like the RTC battery will probably need replacing. I have no EISA cards and probably won't since I don't especially need them. I'm wondering if I should scan & upload the manual? That doesn't seem to be online anywhere, just the II and III versions. EDIT: Yay, found the Manual online after all, shame I couldn't find that before I purchased it. Having the physical copy is very nice though.
Additionally, I got hold of a CD-ROM drive - bought primarily because I love the box art, but it's in superb and un-yellowed condition so I guess I should put it to use somewhere:
