Thx a lot for the quick reply! I ordered a HDMI one 
So i almost got all the pieces together for my NAS/Plex Server. The only thing i am not sure about is the LSI SAS card. You said the LSI 9207-8i was the fastest and most compatible but are those cards something that tend to disappear from the market or can i just buy them later when i want to use more than the 6 HDDs my Board supports.
I ask because i don’t see many offers on Ebay on Germany, most of them come from China…
And lastly: i once had a server based on Ubuntu 20.04 and everything ran fine other than the ssh with Putty from Windows to that server. Yes, i could use the terminal, but the remote desktop always failed. Even tho xming and x11 was set up.
Strangely on a RPi 3B+ i could do it…
Has this been fixed? I didn’t want to always connect a monitor to it or rely on the terminal 
Thx guys
