Ars Technica vergelijkt de InWin Q500 met z'n nieuwere Q500N broeder, die vooral voor overklokkers een aantal interessante verbeteringen met zich meebrengt:
From the front, the Q500N hasn't changed from the good old Q500. When we get to the back of the case though, things start to get interesting. The original Q500 has room for one 80mm fan in the front, and two in the back. The problem is that the two in the back are in the top. This is kinda worthless for cooling the CPU, which sits much lower in the case and gets absolutely no benefit from the two fans. To make matters worse, the one fan in the front doesn't get much air into the case due to the poorly designed front panel.
With the "N" series the 80mm fan in the rear has been relocated to sit right next to the CPU. This is a much better design, and it made a huge difference in the stability of my machine when switching cases. There is now only room for a single 80mm fan at the top of the case, which is how I thought it should have been in the first place. Finally, the Q500N has been redesigned to have the vent holes running up and down the sides, as opposed to the old Q500 where they ran front to back along the bottom.
