i use my intel gen 1 compute stick as my HTPC... i have a 4k display but most of my films are 1080P - you can use this as an HTPC, a perfectly good one, just you wouldn’t want to as you like 4K
And an os
No a bad suggestion. A bare bones NUC with j5005 is £150. Would have to add ram and storage on top but would be a good deal faster.
Better get Intel NUC with CPU J5005. https://www.cpubenchmark.net/compare/Intel-Pentium-Silver-J5005-vs-Intel-Celeron-3865U/3144vs3034
Any good for a PLEX server?
