Massive overkill!

That’s a great Home Theater PC. Hook it up to your TV and install KDE Plasma (distro of your choice 👍) then just crank up the global desktop zoom to like 225% and get:

• A real wireless mouse that has a long range (e.g. $10 TEKNET cheapo deal with 10% off coupon today, LOL! a.co/d/02qG1oHO )
• A wireless keyboard/trackpad combo that’s made for that kind of thing (they’re all terrible keyboards—it’s only purpose is to get you through the boot menu/rescue process if something horrible goes wrong). Use SSH for doing any real work on the thing.

Now install Docker and all the containers/servers you want!

I have a ~14yo HTPC with a mostly modern GPU (8GB) that only has 8GB of RAM and four cores on some old AMD CPU. It’s running four separate servers for my self-host purposes and it doesn’t break a sweat.
