I was in a gameroom last week and they had a number of "classic" cabinets that were old school. It made me remember that old school cabinets were often (not always) made with pretty poor craftsmanship. Marquee holders were often just pieces of metal, cabinets made out of plain black particle board, etc. and yeah, no illuminated controls.
I can't and won't speak for the rest of the community, but I'm building my arcade to relive my childhood and play amazing classic games - but also to look pretty and make visitors drool with envy!
I'm putting Novagems on my panel, and while the microswitches aren't as nice as the leafsprings of yore, the feel and look great on my test panel. When my panel illuminates on startup, a goofy grin appears on my face, and the ridiculous amount of cash I've spent all seems worthwhile.
That's my reasoning - pretty intangible, largely cool factor and for making others say "ooooooh...aaaaaaah"
