100% Wrong. The HAF 922 comes with the Megaflow series 200mm fans, which are rated at 700 RPM/110 CFM, same as the 230mm fans used on the HAF 932. The Storm Sniper comes with Storm Force 200mm fans which are rated at 1000 RPM/142 CFM. The RPM of a fan doesn't mean better airflow, all it measures is how fast the fan spins. What matters is CFM, which measures how much air is pushed.
Also the HAF 922 only comes with a 200mm front intake fan, 200mm top exhaust, and a 120mm rear exhaust. The HAF 932 comes with a 230mm front intake fan, 230mm side intake fan, 230mm top exhaust fan, and a 140mm rear exhaust fan. The rear fan has a higher CFM rating on the HAF 932, and the addition of a side fan cools things down a LOT. The HAF 922 has no side fan, which will make temps (especially video card temps) higher. The HAF 922 also comes with negative air pressure, so air is passively drawn in resulting in more dust and making it harder for the video card to exhaust air. The HAF 932 comes with positive air pressure. Read more about positive and negative air pressure here.
On the side of the HAF 922, you can use two 120mm intake fans or a 200mm side intake fan. Add a 140mm or 120mm fan on the bottom and you'll have very good airflow. You'd get even better results if you replace the top 200mm fan with dual 120mm units. This still does not stand up to the HAF 932, which is the airflow king (after using aftermarket fans). On the HAF 932, you can replace the front 230mm fan with a 120mm unit, the side 230mm fan with four 120mm fans, top 230mm fans with three 120mm fans or 120mm fan and the stock 230mm fan, and use a 120mm rear fan instead of a 140mm. You can use a 120mm bottom intake as well, unless your PSU is too long. If your PSU has a 120mm or larger fan, your best bet is to put it on top with the fan facing down, so it exhausts air out of the case. Then use dual 120mm bottom intakes.
NFSxperts - Most of us didn't recommend modding the case. Lots of you people look at the title and draw conclusions. Take a look at my picture, even though the HAF 922 is a mid tower case, it is longer than the HAF 932. Neither case will have issues fitting the largest CPU coolers and still using side fans. CM never said they are releasing another HAF case either.
If you want to get a cheaper case, you're better off with the CM Storm Scout. The Antec 300/900 are junk in my opinion, the 902 is okay but overpriced and incredibly overrated. Same goes for the 1200. Those Antec cases don't have many innovative features, and lose to the HAF cases or Storm Sniper in the airflow category after using aftermarket fans.
