Nintendo Switch
I have 2, one original with the smaller screen (but with better battery, I think? - not the release console). The second is an OLED Switch I bought pretty much immediately once those were released since I was playing a ton of games on it at the time, and that replaced the earlier one which now just sits on a shelf as a backup console. I don't use it for much other than punching/fitness games and the occasional RPG at this point but I got some mileage out of it at least. Also I have a total of 3 pairs of Joycons (bought 1 extra), and I've reskinned 2 of them - one to a clear atomic purple and the other to a clear light-bluish color. Haven't put any kind of case on the Switch body nor do I have any interest in doing so. I think I have a 256G or 512G SD card in it. Since I have 2 consoles (and it's a bit risky to not have backups for a portable system), I'm subbed to NS Online - I've found it pretty useful a number of times. Might get rid of it someday though.
