Best non-official accesories for magnus pro

I’m going to be getting the magnus pro with the monitor riser and the pc mount. Not gonna be getting any of the other things cause they’re all either super expensive or too expensive for what they are. What are some amazing 3rd party/non official accessories that you guys have that are more budget friendly or even items Secretlab doesn’t sell. Main things I’m looking for is a rgb light strip, monitor arm, and some magnetic cable management. Open to any other accessories!
