Is installing Jellyfin on a Ugreen DXP4800 Plus NAS a good idea?

I think earlier comments about NAS not being powerful enough for a Jellyfin server are generally referring to Synology. Whilst Synology software is particularly good, they are let down by poor hardware - notably weak CPUs, low memory. Now that Ugreen are around, I don't think those comments really apply anymore. I know little about Ugreen NAS' but yours comes with a Pentium Gold 8505 CPU - an Alder lake which which will work well for transcoding - https://en.wikipedia.org/wiki/Intel_Quick_Sync_Video. I've got an ancient Synology DS716+ and though it won't do QSV, it runs Jellyfin server absolutely fine for direct play video. I also run JF on an N100 miniPC and that handles transcoding very well as it has the Alder Lake architecture IGPU. Your Ugreen should be great for a decent Jellyfin server imo.
