My setup is smaller, but when my venerable old router died about a year ago, I acquired an Asus TUF-AX3000_V2 where I installed FreshTomato. One can login via SSH and dump all settings for backup. Likewise, individual or all settings can be done on the command line instead of the GUI. I have a script on my computer that reads CSV files with MAC addresses and more to apply changes in an automated way.

Yes, XMPP with proper TLS on the server side and Conversations or one of its forks (preferably fetched from F-Droid) using OMEMO encryption should be good enough. If you are brave or paranoid, give Tox a try: https://tox.chat/

Maybe the first question is what your budget is, both regarding money and time. For example, you could buy a pre-configured NAS from Synology or QNAP, which requires less technical skills but more money, or a home-made solution reusing used components (but fresh disks for reliability). Depending on your electricity costs, you may want to choose a low-power solution or something which you power off when not used. For storage, maybe a three-disk RAID5 is a good compromise. For backups, plain S3 cloud storage encrypted via restic is a good idea.

Mal als Beispiel wie das in anderen Ländern (Schweden) gemacht wird:

Das da ein freundlich-lächelnder Mann in rot steht, ist nur fürs Pressefoto. Normalerweise Selbstbedienung. Der ganze Apparat kan in der Höhe eingestellt werden. Vorne die Fläche ist für eine digitale Unterschrift, die auf die Karte gedruckt wird. Bezahlt wird dann per Bank/Kreditkarte. Alles papierlos.

Gibt es da nicht da nicht die ganzen Rankings von Zeitschriften (Focus, …)? Was Schulen angeht, Bayern vermeiden. Da habe ich schlimmes gehört. Da herrscht (pedagogisch) teilweise der Muff der 1950er Jahre. Gebiete, die von Klimakatastrophe (Dürren, Überschwemmungen, Küste) betroffen sind, meiden. Fahrradfreundlich (flaches Land, Fahrradwege) und/oder guter ÖPNV ist ein Plus.

Many projects accept donations, for example for server costs or travel expenses (conferences, meetings). You can setup recurring monthly transfers to projects whose software you use most often. Examples are the Free Software Foundation for various GNU tools or the KDE project.

#Peertube got already mentioned, but just serving video files may already suffice. Modern webbrowsers are capable of playing videos. Some tweaking of parameters may be necessary when encoding them. Also, no frills such as dynamic adoption of bitrate/quality or high-level stuff like commenting, likes, or subtitles.

Most comments comments mention Brother, but for me, Oki is working like a charm. Using a B431dn (b/w, duplex) and a C531dn (color, duplex) with PPD files from OpenPrinting. Older models though, not sure if Oki dropped quality in favour of DRM since.

Rules of thumb:

1. Laser instead of ink unless you specifically know that you need/want ink.
2. Stay away from HP, Canon, and probably Epson. HP, like IBM, has long lost its aspiration for quality.
3. Stay away from anything that is ‘smart’ or ‘cloud’.
