Not exactly Disney plus but I had a similar issue regarding downloading Netflix shows to an SD card. There’s a setting in Netflix to download to SD card however even if you select it, it won’t work. You have to enable USB debugging and manually force the Netflix app to have SD card access. It’s insane.
It really kinda depends on what type of Minecraft server you’re running. I was running Plex and Minecraft on unRaid with like 16gigs of ram and an i3 8100 and it was fine until I started doing more intense moded Minecraft. The iGPU in Intel processors can handle transcoding really well so it’s a pretty good all in one solution. I imagine if you’re going to heavily modded Minecraft you could probably get away with a current gen i5 or maybe even i3 if you’re on a budget. Looks like the i3 13100 has hyper threading and my old 8100 didn’t. Not sure how big of a difference it would make.
I’ll keep using it until they no longer let me, I guess. Pretty sure OMV and TrueNAS have matured enough to fall to if unRAID decides to go full subscription, at least.
