Compatibility with Android usually means running DAVx⁵

A larger package than just CalDAV and CardDAV would be to look into Gromox with Grommunio-DAV.
It’s on my “I should check this out” list, so no personal experience.

They also have support for Exchange ActiveSync through another optional addon

The Catalyst 1200 is a small Enterprise switch and the Business CBS220 is meant for SMBs and they seem to be extremely similar in what they can do.
The catalyst has some limited routing abilities that the business switch lacks, but that is all I can find and it’s honestly not enough to influence a decision in my opinion. It’s not like the Catalyst 1200 is a true L3 switch either.

I imagine it will mean that port 3+ will stay USB-A in many cases

The tool mentioned is “Davinci-Helper”, not DaVinci Resolve. Davinci-Helper is a helper tool for Fedora and Nobara users to get Davinci Resolve working properly.

Uncertain what you mean with extract the information.
The install information is here:
https://github.com/H3rz3n/davinci-helper?tab=readme-ov-file#how-to-install-davinci-helper-on-fedora-based-distros
A more in depth guide is found here:
https://github.com/H3rz3n/How-install-DaVinci-Resolve-in-Fedora-Linux

That tool is for Fedora and Nobara, not MX Linux.

I didn’t mean for you to take the linked requirements as software recommendations but as two programs that can offer you a guideline for hardware requirements. If you just want to do 2D animations then you can get away with much less power.
I do believe MX Linux is based on Debian 12, so it should have a slightly old version of Blender available.

It is! But there are unofficial ways to get it to run on other distros too, such as

Here’s the reqs for Blender, another software that might be of interest

I imagine something like this:

Followup; Not as cheap but there are M.2 to SATA cards available too, if your mb has no empty PCIe but do have empty M.2 available.

Might also look at larger drives. When I compared 3.5’’ drives then the 24TB is cheaper per terabyte than both 16TB and 12TB. The ones I compared are listed below:
Seagate Exos X24 Harddisk ST24000NM002H 24TB 3.5" Serial Attached SCSI 2
Seagate Exos X24 Harddisk ST16000NM001H 16TB 3.5" Serial ATA-600 7200rpm
Seagate IronWolf Harddisk ST12000VN0008 12TB 3.5" SATA-600 7200rpm

That’s very true, I’d rather by an ASUS or other known brand N100 MB + an M.2 to SATA splitter too, if the price is equal (or better).
Last time I looked at it I was looking for hw for an opnsense router so I wanted the multiple intel i226 nics that most china-brands add on, so my mind went that way right away.

For the easy way I would just grab a Synology DS224+.
For the DIY something like Jonsbo N2 case + a N100/6xSATA mitx board from china should do the trick. The N100 is great for low power builds.
