2012 Macmini Server for remux files

Hi guys,
I am setting up a 2012 macmini as a server and client is the Apple TV 4th gen. Simple 2 questions.
macmini: 2.5 intel core i5 Apple tv4: wired connection
Typical remux:
Size.................: 29.4 GiB Total Bitrate........: 33.58 Mbps Container............: MKV Codec................: DTS MA/Core Bitrate..............: 5216 kbps kHz/bit..............: 48 KHz Channels.............: 7.1 Language.............: English Codec................: AC-3 Bitrate..............: 224 kbps kHz/bit..............: 48 KHz
Would the mini handle transcoding and serving remux files
Would I notice the remux quality at original settings.
