i have a pc i built as a "spare" for my ol' man, i dont have any spacers. for the motherboard, so i screwed the board directly to the case, it has kinda built in spacers it looks like, some parts of the metal are "up" so it kinda sits above the rest of the case, so all the motherboard isnt touching the metal, will this be ok, or should i get spacers, i havent powered the machine on yet, cuz i dont wanna blow my crap up lol
