for uploading, absolutely use syncthing. you can set it up so that it works in only one direction, i.e. phone to server, so any file that appears on the phone’s download folder gets sent to the server. the one you want is syncthing-fork on fdroid.

as to listening to the music via youtube check out innertune, also on fdroid.

As of right now, Plasma Bigscreen isn’t available for public use yet.

which ones?

like a commercially available one? negative, you have to tinker and make it such.

if you have linux on the player (like with said PC or Raspberry) you have full control and can set it up to boot directly into jellyfin-media-player in fullscreen TV mode (that’s the one where remotes work).

Raspberry Pi with a cute case then, and/or glued/velcroed to the back of the TV. they also support HDMI-CEC so your TV’s remote can work.

stove them out of sight? well, you can go for a mini-PC if price isn’t an issue. but these things can be had for ultra-cheap, especially if you have one laying around or get one with a busted screen or sumsuch. an android box is a hit or miss, maybe it’s good, maybe it’s crap, maybe it’s loaded with malware… the middle ground would be a Raspberry Pi, there are unofficial LineageOS Android TV builds.

an old laptop/desktop (like 6th-gen Intel or newer) that boots directly into jellyfin-media-player in TV fullscreen mode. it supports any remote that can emmit up-down-left-right, enter, esc (like, via InputRemapper). disable transcoding on the server and play anything you want via direct stream.

they are widely available and cheap.

yeah, those are too big. was hoping to score an ITX-sized abandonware for cheap and retrofit it with a 10 TB or so drive. I had this thing many moons ago:

it could fit a drive, with some wiggling and swearing. so I figured maybe something similar exists. building it from new parts is way, way out of budget.

edit: this is how it ran for close to a year.

this isn’t addressing the technical side per se, but consider your user’s rebelling factor, i.e. them passively resisting using the stuff you provide and sticking with corpo-crap.

not to go into details, but I’ve got a number of opensource solutions in place for various clients. we have huge some issues with users who need to be corralled and coerced into using the provided messengers, web portals, and such. some resist out of habit, other’s because they prefer the infinitely more polished UX of assorted spyware as opposed to the janky feel and rather rudimental features of opensource alternatives (think gmail vs roundcube).

no help to you, but my god is it convoluted and complex; every year or so I look up if there’s been some change in that regard and every time I stop reading halfway through the setup instructions. maybe next year…

“or else”. and raise your eyebrows (practice in front of a mirror).

on a more serious note, if you set it up via docker on a VPS, you have a portable solution that can a) be easily scaled within the provider’s infra and b) be transferred to on-premises bare metal, should the need arise.

I deployed RocketChat on two different client installations (didn’t check the licensing you’re mentioning, I’ll have to look into that) and I run a Prosody instance (XMPP) on my own; tried Matrix for a short while and ran away from that mess as fast as I could. anyhow, although the messengers work without any significant issues or downtime, the amount of flak I get from non-tech normies about the client apps is staggering.

the apps just aren’t up to current UX standards. they’re used to Twitter and iMessage and Telegram quality UX, and getting used to these PoC-quality apps - both on mobile and desktop - makes them “feel icky”. I’ve had to intervene on a number of occasions when some of them transferred their business-related comms to other platforms because they just can’t/won’t get used to these apps.

regarding the pricy enclosures, there are vastly cheaper eGPU solutions especially if you’re able to utilise the on-board M.2 or mini-PCI slot. if you don’t move the laptop around, it’s a viable option. this would be an example - not an endorsment. you’d need a $15 PSU to power the graphics and it works well in linux, with the hotpluggability being the primary issue; if you’re willing to shutdown before attaching the eGPU, close to no issues.

you can run it as graphics card (i.e. utilize its display outputs) or just use the laptop’s display with optionally switching between the onboard and discrete graphics.

using rsync:

why not btrfs send | btrfs receive? is there some advantage to rsync?

did you hotswap the drives after each btrfs replace or shutdown and then swap?

what’s your host OS and do the drives spin down if inactive?

thanks for the writeup!

I’ve set up a local mail archive with just dovecot + imap plugin. you don’t need the full mail server with postfix and whatnot, as it’s not intended to send anything anywhere, or even receive anything for that matter. it just sits there ready to be searched with thunderbird, no need for other complex solutions you’ve mentioned.

I wanted to write the same thing. have the notes app do the notes thing and handle encryption elsewhere.

as to apps, I suggest QOwnNotes. it’s markdown, highly configurable so you can make it minimalistic AF, stores notes in invidual files and folders. it also has a bunch functionality like syncing to nexctcolud and such, but I’d advise against it, just use it as a notes editor. you don’t have to selfhost anything, make it use the e.g. Documents/Notes folder and you can use syncthing to securely replicate it to other devices.

first off, if you plan to scan the storage for bad “sectors”, that’s gonna take eons if the disk is of any considerable size. what’s more likely is you running the SMART self-test and that will work over any medium.

the cables absolutely can and do cause corruption, whether it’s plain SATA-SATA cables or the USB-SATA with their own controller on it; however, if you don’t have reason to suspect this particular cable/adapter is faulty, it’s not a worry vector per se.

I have acknowledged that they’re that, but that’s not what OP asked for - they asked for a cheap setup (which the minis ain’t) and they intend to run a servarr instance, which implies large storage and those are both difficult and not cheap to cram into said minis.

I don’t understand the fascination of other commenters with mini-PCs, as the mini-ness was mentioned nowhere in the OP.

any used and decomissioned old office PC, any i5/i7 is way more powerful than you’ll need for that setup. you get everything you need right in the box and you can cram it full with cheap RAM and hard disks. you get to repurpose something that’s useless as a desktop workstation and not buy more future e-waste.

yes, the mini-PCs and the Rpis are more power efficient, but the operating costs of a $30-50 PC don’t come close to the price of buying one of these mini-things, not to mention - figuring out how to run large hard disks with it.
