Re: minimum distance between cooktop and cabinets
I have to agree with Havana, a 1/2" isn't going to make any difference in the performance or safety of the cooktop. You also likely aren't going to find any pots that come near that height either, unless you're using industrial pots and pans, then you'll also quickly find that your residential cooktop isn't going to cut the mustard in heating a pot of that size anyway.
I suffer from CDO ... Its like OCD, but in alphabetical order, LIKE IT SHOULD BE!!!
