I think someone even photographed the inside of the Belkin variant, and the motherboard still has the same contacts the Linksys variant uses for its additional LEDs, they are just unpopulated. (claimed but w/o photo) In theory you could add your own, but that would be quite a project to make nice-looking holes in the case for them to be visible.
I would disagree about the attractiveness, but it is amusing you mention "eye-catching"; I intentionally sought out the Belkin variant to make it blend in on a white shelf. Fortunately it was also noticeably cheaper at the time.
