Uhm, no, that's not boring. I love seeing people's builds, even "simple" ones. There's always something interesting that can be gleened from another builder's process. Especially when it comes to cable management.
Very interesting breakdown. As for OLED burn-in... it is wayyyy overhyped, and I really don't think there should be any concern these days. Most especially because once the monitor is turned off, almost all of them now do their "cleaning" processes to further prevent potential pixel burn issues. If anything, the first 200 hours try and "be gentle" since the OLEDs are burning at their brightest and hottest. A good level of vareity on the screen would help balance the phosphors until things "settle". Even so, I don't think it's necessary. After 200 hours... just let'r rip.
I see burn-in a potential issue if you ONLY have the same screen (or logo) displayed, day in and day out, and it would still take MONTHS before burn-in might start happening.
I did the same thing with hiding the Taskbar, and I had the icons on the screen, but I would cover them when I had a window up. I would shift the window(s) around every 10 minutes or so, and I still have a black background but that's because I prefer a blank black background.
With that said, I have about 5000 hours on the LG OLED 48" 48GQ900B (main display), and not a peep of issues. I no longer hide the Taskbar, as of a couple months ago. My OLED C1 (second monitor) is usually used to watch videos while doing other stuff on the main monitor, but it, too, has zero problems. That has at least 8000 hours of use at this point.
I haven't even come across image retention on either screen, which is impressive.
