I took a fiver break and pulled the board out and had a lookiesee.
The thing has 4M ram sticks in it, so I am assuming that probably
indicates 32M ram on board.

Looking at the back of the case there are 3 hd50 scsi connectors.

If I am reading them correctly, one goes from the cpu to the case
to cpu connector?

One goes from the external connector to external devices or a scsi
terminator goes there (top connector on the back)?

The cpu is a 501-1316 rev 03.  That seems like a reasonable board.

The frame buffer is a 501-1402.  I did not find this in the faq.
Is this a frame buffer from a 3/80 machine?

That is all I see, offhand.  I was unable to get deep enough to see
what HD's were there.  But, for the sake of discussion, if it has
2 or 3 internal drives, full height, how many half heights of say
2/4/8 gig could I drop in if I wanted to give it some server type
play space?

Yeah, its slow and a bit of an ugly duckling, but not near as ugly
as the 3/160 crate I also run.

Thanks
