This is my understanding and the reason I even asked in the first place.
I was also aware that some arrangements do work singly, but I lack the
experience to identify them.

My intention is to get this machine up and running for no additional
outlay (although I may end up dropping Linux Emporium a few quid to
ensure I get an up-to-date distribution).

I have a 486DX4/100 mobo that I was given, but it has no case.  I have
the Blue Lighting that I obtained for free, apart from having to buy its
owner a new PC.  The IBM case is unusual, like an ATX, but I don't think
it is one as the card slots are piggybacked on top of the mainboard.

The DX4 also has 8MB of RAM, comprising 4x1MB in 30-pin slots and 1x4MB
in a 72-pin slot.  I know that this memory configuration works at a
reasonable rate on that board as I used it briefly in my main box when I
upgraded from a 386DX25 a few years ago.
