Gamer gift?

Do you have any ideas for a great birthday present for me? I gamble a lot and often. I'm actually open to all genres of games and also to hardware. I'm more than satisfied with my PC and the keyboard, mouse and headset are also pleasant. I also have an Xbox one S, lots of games for both platforms. Up until now I had thought of the Switch or a tablet for writing in school.

An SSD or a couple of fancy fans could never hurt.
