The BTX, or Balanced Technology Extended, system architecture spec has been around awhile now, but it's been pretty quiet. Usually these things take a big name or two to get started, so Gateway thought they'd kick it off this September. The chassis on one of their their up-and-coming desktop series will feature the BTX architecture, which allows for extremely efficient cooling by getting all their ducks in a line so to speak, blowing air over horizontally aligned memory chips and upturned expansion boards, then over the chipset and CPU. So it's kind of a win-win situation for both you and Moore's Law. If none of this means anything to you, that's okay, you'll just notice that your PC will be a little bit cooler and quieter.
