TTGI-USA famous for making some the highest quality PSU's for the money, also makes some of the highest quality cases on the market, and their aluminum model rival or surpass the quality of Lian-Li. Certainly the price is much more affordable. Today were looking into TTGI's new X-Mask case. Personally I own their TT-261T2 brushed aluminum 5-fan model, and love it. My second rig is housed in their steel TT-561T2 and both are excellent cases, and possess some of the best airflow dynamics of any case I've owned. Albeit steel or aluminum, TTGI puts the same high quality craftsmanship into all their products. Their new X-Mask case has many of the same User-friendly features found in other TTGI models, and this particular unit is manufactured in steel.
One should think of their PC-case as very large heatsink, because that's exactly what it is. Every device within your case which requires a heatsink and fan (HSF) such as the CPU, North Bridge, and graphics card are all sources of heat. The heat these devices produce must go somewhere or the air-temperature within your case will continually rise. This would have a detrimental effect on system performance and eventually parts would overheat to the point of failure. If one’s case were simply an enclosure, what you would essentially have is a very expensive Easy Bake oven. Astute case design treats the case, and the components within it, as a symbiotic system. If a case is designed properly, it will constantly draw in cool air and expel the heat generated from system components. The volume of air within your case must be removed before the devices within the case begin to heat that air to dangerous temperatures.
And this ratio is what separates mediocre cases from great cases. The X-Mask allows placement of a rear 120mm fan which is much more effective at removing air then an 80mm or 60mm fan would. The fact the 120mm fan has larger blades means it doesn't have to work as hard as the smaller fan, it requires less RPM's to move more air, and RPM's equate to pitch, which is the primary source of noise in any system. The X-Mask utilizes twin 80mm front intake fans, and the end-user should place a rear 120mm fan for optimal cooling. When the case is sealed, an air-pressure is established, and it's this air-flow dynamic which will make all the difference. The idea is actually quite simple, the cooler your PC runs the better it performs.
