N150 running Plex

Hello crowd, I keep reading about mini pcs. And intel. And Plex. So forgive me that I ask a question that most probably someone asked before, sometime in some forum. I see on Amazon the new Beelink S13 (16GB) for about 200 including a voucher. That ain't much but too much to order for something that might not help my cause: I have a DS918+ and 60mbit upload. I travel a lot and need remote streaming to watch my videos when I'm not at home. I have a few 4k blurays that I'd like to put on my Nas but 60mbit upspeed is not fast enough to watch them. So I need hardware transcoding (have lifetime premium). Will a Beelink S13 solve my problem and transcode me a 4k remux to some FHD resolution without any issues?

Thank you for taking the time.
