One oddity about the Sol-20 is that the S-100 cards were mounted horizontally, unlike many other S-100 computers of the era where they were mounted vertically. They wanted to keep the whole case low profile and oddly that was because they had fixed height wooden sides because the company sourced the wood from a gun stock supplier and it had a limited height.
It is not ideal for cooling as the heat builds up between the S-100 boards. On my Sol-20 I added an extra fan to combat this. In my computer I run three 16k ram cards so I can run 48k CP/M and the heat between the cards is an issue. Also these cards have issues with their digital delay lines.
Here is an article about the cards, if you go to page 24 you will see the cooling fan I added:
