The term you are looking for is “parametric”. You might be able to find a design you need through the many 3D printing file sites using that term. FreeCAD and Fusion360 are open used but another is OpenSCAD if you are more programming savvy than modeling savvy. There are plenty of recipes for threads in there to make your relatively simple design request here.

Tons of good and free options, you just gotta pick which one looks easiest for you.

Keep in mind that any hobby printer, especially those under ~$/€1k are subject to needing some level of tinkering to get reliable printing. If speed is unimportant, any of the options you provide will be a good fit. You will benefit from running some basic tuning for each spool of filament to get the best print quality. The speed can be dialed in to reduce failures but not take forever.

Build plate finish is more of a personal preference when it comes to PLA. Textured plate will provide slightly better grip to prevent the print from popping off mid-print, but it’s a visible and tactile texture to that surface. It would probably be best to have a both a texture and smooth plate on hand long term.

Enclosure mainly comes into play if you print high-shrink materials like ABS or ASA. If you don’t like to tinker, I wouldn’t try to enclose a prusa or ender and would save up for a design built for it. If you don’t mind tinkering a bit, you can always add the enclosure later.

Buying a used printer isn’t a terrible option, but I would get eyes on first to ensure it prints as-is, especially since you want it to be plug and play. People sell printers for a variety of reasons such as upgrading, lack of interest, lack of funding, etc.

It’s too early to know how exactly it’ll be implemented, but I’d bet there would likely be a toggle/setting to turn on at the very least. I’m sure the upgrade instructions will be early laid out how to enable it.

Yes, the seller was Topton Computer Store. No complaints from me on the purchase/process!

I use a similar one of these (different io panel and case) for OPNSense and it’s been a delight. Not sure how well it would handle Plex but if you don’t need to transcode the files it should be fine. I bought one without ram, os, and storage for $150 last year. That listing isn’t available anymore.

Having had both great and terrible work out days, I found what led to the good, enjoyable days was purely the mindset. HIIT on a stationary bike sucks, but I had some fun sessions when I turned it into a game. Weight lifting routines can be super boring, but changing from rep based to time based and seeing if you can crank out a few more reps without sacrificing form can make it fun.

It takes a lot to get into that mindset for me, but it’s possible and it makes a world of difference. Gamification of any task can introduce a challenge and give oneself a better purpose in the moment.
