LibreElec/TVheadend running on Mac Mini in Virtualbox?

Is this a crazy good or crazy bad idea?

Why do it?
1, I need a pvr backend
2. tried mythtv on the mac mysql was a pain and conflicted with my VPN service and smb. Could never get it all to play nice and work.
3. the mac is always on and serves my media from 2 external drives, Torrent downloading and general media management.
4. there was no new hardware for christmas must use what i got.

thanks for the advice
