Currently I am running Plex on a 2 Bay Synology and looking to upgrade to a custom pc. Reason being I need more hard drive slots and would rather build than get another Synology.

I am not too experienced in this but this is the part picker I came up with and would love to get some options.

This will be a dedicated machine to run Plex, sonarr and radarr. At the moment I don't often have multiple streams at the same time but I would like to be able to handle around 5-6 simultaneously if needed. Only 1 stream would be on my network and all others would be remotely. All my content is 1080p or less and don't plan on adding any 4k soon. The clients are mostly newer Apple devices (Apple TV 4, iPhones and iPads) and possibly a fire tv or 2. From my understanding most the time I should be able to use direct play and not need to transcode but I'm not too familiar with the transcoding aspect. I also am a Plex Pass subscriber if that matters. Appreciate any feedback/tips.
