This little snippet covers how to get Syncthing to run in background on boot regardless of Desktop environment (so that you've got full synchronisation even in default game code), might be worth adding it under the link to Syncthing. :)
In case anyone looks to put SSDs in their Reliant box, this 2.5" to 3.5" bracket aligns the SATA power and data into the same spots as on 3.5" drives, allowing you to put those smaller SSDs into Reliant's drive brackets. :)
I've actually purchased one second-hand recently, and in the process of setting it up with some infrastructure! So far managed to set up ProxMox with Home Assistant OS running in aVM, and it works wonders. :)
I'm looking at modifying its specs a bit - currently the only place I can set it up in is a living room, and the PSU fan proves bit too loud, so I'll be replacing it with a Noctua one; and for other noise-reducing means, SSD as the main operation drive, spin-down on idle set up for the regular HDDs, and a set of padded rubber "legs" to stand on to reduce vibrations. :)
As far as my experience goes, all of the official content (base game, expansions, and smaller DLC) is fully playable on the current version of the engine 😁.
OpenMW is still marked as 0.x primarily because of the editor - while the game runtime is in fully playable state, OpenMW-CS is still lacking some features compared to the official Construction Set, and the parity of the tooling is required for them to mark the project as 1.0.
Of note, while many mods work fine with OpenMW, not all of them do - some break on bad scripts (OpenMW is notably more strict on compilation errors), and anything requiring the use of the executable extenders (MWSE/MGE) is not compatible at all (adding support for the functionality they provide is considered post-1.0).
