My home setup is:
- home assembled PC, 4 core CPU and 16 GB of ram
- Ubuntu 14.04
- ZFS (8 TB)
- MakeMKV and Handbrake
- Ruko box attached to the TV and home network
Total one time cost $1500.00
Sure Plex is charging $40.00 per year but notice I control the entire setup. No one throttling the bandwidth between the Plex Cloud and my TV and no one selling the information about my DVD / Blu-Ray collection to advertisers.
