[mythtv-users] Old Mac Mini vs RPI as frontend/backend

[Ken Mandelberg]

I have a 2009 Macmini running Ubuntu serving as both a front and back 
end for Myth, with a very large USB drive for the media. As far as the 
backend it runs well despite having accumulated years of database 
entries, and the frontend works well because of the Nvidia 9400M. It 
also has 8GB of ram

However, the internal drive does have some bad blocks, and I'm thinking 
its time to move on. I also hate jumping through hoops with refind and 
its booting scheme to work around Old mac firmware.

Would an RPI 4 be an adequate substitute?

The maximum 4GB of Ram seems like it could be a problem for the backend 
functions, like mythcommflag, running concurrently with the frontend. I 
also don't know how the Myth GPU support for RPI stacks up against 
Nvidia 9400M/VDPAU

Suggestions?
