The impact from hitting water at such velocity would kill them.
Drop them 100 miles out with nothing but their clothes instead. That would be a much more horrific experience; being able to tread water for a while, but nobody being able to find you.
It would be an incredibly painful death. Magma/lava is incredibly dense, you would skitter along the top like a drop of water on a searing hot pan. And then pop.
Ah, that's a good point. The full tower version has space for that, though.
I'm not saying you should get an Optiplex 7050 specifically, but a used office PC tower (like an Opitplex, HP Elitedesk, Lenovo Thinkcenter, etc) can be picked up for under $500, ready to go, and has more than enough processing power to handle the loads you're asking of it. Plus, they usually have Intel's AMT management option (aka "vPro"), which allows you to remotely manage the PC even when it's powered off.
Ah, ok, I get the general idea now. UCCU uses this software, too (you said you worked for MX, which is based in Lehi... I also work in Lehi 😅), but I gotta be honest - I'm not a huge fan of the mobile app. It just feels like a PWA. But that might just be UCCU's implementation, so, IDK.
My only beef with LubeLogger (and it's a pretty minor one, given it's just the one dev) is the lack of a mobile app. I've used aCar since 2012. I have years of data logged, and IMO, having periodic reminders and widgets available at a single tap is a bit more favorable than a PWA.
I am very curious about ntfy though. Please do share.
First and foremost: Do not expose your host system or the OMV admin interface to the internet. Ever. Doing so is only asking for trouble. Only expose services that have been properly isolated from the rest of the network and host system. Everything else you can access via VPN, or locally.
Secondly: OpenMediaVault beginner's guide by DB Tech. Him, Craft Computing, Hardware Haven, and a few others whose names currently escape me, are all solid sources for learning how to host things at home.
After OMV, I would start with learning Docker and other containerization methods, and VMs.
