So I have a somewhat large project on my hands here. The main idea for the project is to complete rework my current media setup to utilize an HD Homerun prime to record shows to a nas for playback with plex. Currently the plan is to hook up all of the tvs to chromecasts for playback. Now where I am not very knowledgeable is in setting up recording. I would like to be able to just set shows to record and have the hdhomerun pass them to the nas but I do not think there is anything like that currently, so will I have to build another pc to do the recording running something similar to mythtv? Also I am considering rack mounting the nas along with my pfsense router so I would appreciate recommendations for a small rack or cabinet with anything around like 8 units of space, or is that just a bad idea? I have a budget of like $2500 and I already have a 2u router and the chromecasts.
