I'd say get him an upgrade for his setup. Cool lights, Poster etc. Nanoleaf Is always a good option for lighting but it comes at high cost... Maybe you can find cheaper alternatives on amazon. I found this for example:

https://www.amazon.com/Jizbuger-Lights-Ambient-Lighting-Gaming/dp/B09CGWNXV1/ref=sr_1_7?crid=2NL4Y8WAD2REB&keywords=gaming+lights&qid=1671509503&sprefix=gaming+light%2Caps%2C135&sr=8-7

I actually sell lights myself online. However my shipping time can't keep up with amazons.

If you ever have need and more time for a gift considering my store might be a valid option...
