I put an Apple sticker on mine. It’s held up well to humidity and heat. Don’t know about the case though

1. I’ve found that with Decky, if I haven’t full power cycled the system in a while, it gets a little buggy. I think a restart might help.

2. For any third party apps other than Steam and GOG, Lutris works best.

3. PC Gamepass and Microsoft store games still can’t work because they are .uwp or Universal Windows Programs. Cloud streaming is your best bet for now.

Hope this helped
