It turned into quite the adventure, and when I finally got it working, I thought I'd write up the settings for posterity....

In the spirit of consolidation that underpins this blog,  I thought there must be a way of tidying all that up. So I started with a svelte computer case and starting adding stuff in until I was happy.
