That's why I still use a ~15 year old Supermicro server chassis with desktop foot kit on it lol. I've upgraded the innards 2 or 3 times so far. Has 8 hotswap bays, tons of room. no fucking RGB or "windows" or any of that bullshit.
I just built an i9-13900K replaced the LGA1366 2P board in it. It's an astounding performance bump, to mildly put it lol. I plan on using this chassis with this setup for probably another 5-10 years before upgrading again.
The board having Gamer-RGB should not be a problem as long as you can disable it on the BIOS. It would be like any other "extra" hardware your board has that you don't use (for instance, extra headers for front panel USB ports you don't have, or more SATA ports than you need).
The case having a transparent side panel, on the other hand...
My biggest gripe with most lowend-to-midrange motherboards is that they practically always have disappointing rear I/O, which is ridiculous to me particularly on mATX/ATX boards, because part of the point of having a desktop instead of a laptop is to have a ton of ports and little to no need for hubs/docks/etc.
So I tend to end up buying something on the higher end even if I'm not using all the board's features. My current tower uses an ASUS ProArt X570 Creator.
