So it depends in how many individual drives you want it, I am from NL so that's where I draw reference from.
The lowest $/TB I have seen have been on 18TB drives new(HC550's) which had an insane deal for 200 euros a piece(For new drives with warranty etc this is basically an insane deal), which means it's 11.1 Euro/TB so the cheapest way to do that assuming you do raid0(so 0 redudancy if 1 drive fails you lose everything) it would be 9 of these drives(162TB).
So assuming you don't want 0 redudancy I would say on an array of 9 drives you would do(depending on what your focus is on you would alter how many vdevs etc) 2 drives of parity(raidz2 assuming your using ZFS/RAID6 in others), which would mean it would put you to 11 drives which would at this "best price" would be 2200.
Generally the best no deal price I have seen is around 300 euro per 18TB drive,so assuming you do that deal the no redudancy array would cost you 2700, and the array with 2 drives of parity would cost you 3300.
Do realise this is dutch pricing, which might vary widely from where your from. And this is buying new and you can generally find recertified drives cheaper while not necesarrily being worse.
I also recently installed it on Tizen(Samsung's OS) and using the docker container(https://github.com/babagreensheep/jellyfin-tizen-docker) it was stupidly easy and the hardest part was enabling developer mode.
I just use my domain inside my network which is a .net
So the only thing I will say is that the problem with a "DocuSign" alternative is that docusign is more accepted within the proffesional community and when docusign says something was signed it's trusted. In this case what is to say you don't modify the data or something similar, I know you could send out a confirmation e-mail or whatever but you get my point.
But ofcourse I will always take more apps that can be selfhosted :D
Well... answer is I didn't know NTFY had a built in SMTP server. I just used this combo cuz before I used it to send my notifications to discord which mailrise makes easy. I will say that mailrise does let you more granulary define what e-mails will be sent to what topic while NTFY just uses the recieving address as the topic which might not be wanted.(I can for example define stetsed@* which means it doesn't matter if I use one of my other domains, or father@* which means he could use whatever domain he would want).
Honestly I do love tailscale, but every time when I start using it I am just like... meh. I don't need a bunch of interconnected as I have 1 homelab, and for other stuff like my backup system it goes over v6 so there is no NAT to speak off(just a firewall). And for any remote devices I just use plain wireguard including my always on VPN on my devices.
However I will continue to recommend Tailscale to people who are new to selfhosting and don't want to deal with all the networking bullshit, and hey if you want to not be reliant on the tailscale control server host headscale.
