do I need to worry about transcoding??

[ed]

Considering your usage scenario, transcoding may not be a pressing concern for you. Since you primarily utilize Plex on your local home network and seldom stream remotely, the necessity for transcoding is likely minimal. Moreover, your Roku smart TV's native compatibility with HVEC/x265 files diminishes the need for transcoding. Given these aspects, a NAS featuring a Celeron CPU with a built-in transcoder, such as the DS423+, should suffice for your requirements. Celeron CPUs equipped with transcoding capabilities offer efficient performance, making them suitable for serving Plex content to devices within your home network. Additionally, investing in a NAS like the DS423+ within your specified budget range allows you to expand your storage capacity to accommodate your growing collection of 720p and 1080p files.
