Yup, I'm going to be using 3/4" fiberboard and t-molding. I'm heavily considering using a thinner piece of wood for the top, like 5/8" then using 1/8" Lexan, it might cost more though, vs. using the extra wood from the cabinet sides for the control panel top... but I think it might be worth it to just cough up the extra cash. There was also a mention of angled cut along the bottom, to make up for the slack, which is also a good solution... but I'm definitely leaning toward the 5/8" topsheet.
ps, if you guys want some free comedy, go to Home Depot or Lowe's and asked where their 1/16" slot cutters or 1 1/8" Forstner bits are... the blank looks are priceless, literally today, "I ain't never heard of that." LOL I found my at the local OSH, but I'm assuming ACE would have them too.
