Hi I installed Armbian and happily browsing internet. Suddenly the screen went black. I could not bring back any screen so I rebooted (pulled plug!) - The machine is back but now I cant connect to internet. I can connect to wifi not internet. I will try Ethernet tomorrow when I am home. Any idea how...

I found the top really flimsy but does the job ok...

There are a couple of cases on Thingiverse. I printed one but really it is too flimsy. I am not sure I want to spend time drafting my own, however. I will leave it just attached to the aluminium heatsink, this is fine for time being for me...
