I'm running a Maxtop Singnature Series II Grey at 1/3 cooling capacity about 5C (mainboard) cooler than my old case at full capacity.
I can't wait till my new parts come in the mail. I've got a 120mm fan that will replace the really old 80mm in the back, I've got 2 adapters coming that will allow me to use the side-mounted 80mm, and the front 60mm that blows across the HDDs.
Really the only two fans I've got running are the 80mm top-mounted, and the old 80mm rear that I took off my old case. Yet it still remains 5C cooler than my old case (my old case was usually 35C, although it would often get up to 40C, this case is 30C round the clock).
I like the look of the Maxtop as well. It just has a simple design, nothing too fancy, which is how I want it. It is unfortunate though that Abit boards do not offer front-mounted USB ports.
