I currently have a headless server, running Openmediavault.
I currently use TVHeadend to schedule and make recordings from the FTA channels available via the tuner cards that I currently have.
I did consider a TBS Quad DVB-S2 tuner card as a replacement/upgrade but have been advised that TBS cards are pretty tricky with Linux as kernel updates mean that the drivers have to constantly be recompiled.
SAT>IP servers seem to get round this problem buy existing as a separate product and feeding the satellite signals directly into the network, where they can still be picked up by my server.
I am currently looking at this one:

But reviews seem a bit thin on the ground.
