InWin is a long-established Taiwanese electromechanical manufacturer that has focused on the production of chassis since 1985 and is also the foundry of Dell, HP and Lenovo. While InWin covers accessories such as chassis and power supplies, its flagship store in China currently only sells computer cases.
 
Because of its exquisite materials and more durable than cases of the same price, InWin is very popular in the DIY world. Due to years of accumulation of chassis design and production and processing capabilities, InWin will launch a concept case at Computex Taipei every year, and DIY enthusiasts are guessing that the popularity of the new concept case is comparable to guessing the new Apple.
 
In fact, there are not many chassis in service for sale every year, which are divided into concept-level, high-quality and consumer-grade. The price of the concept-level chassis is as high as more than 10,000 yuan, and the cheapest D-FrameMini is priced at 1780 yuan, the overall appearance is composed of aluminum tubes, two special-shaped tempered glass on the side, and can be equipped with Mini ITX motherboards, and the maximum support is 240mm water cooling radiator and 165mm high air cooling radiator. This chassis has almost no shortcomings, but it may cause the aluminum tube frame to peel off the paint or the glass to crack during logistics and transportation.
 
In the consumer-grade case, the Inwin 301 and 303 are more eye-catching. Both are mid-tower chassis, with the 303 supporting standard ATX motherboards and the 301 only supporting motherboards below MATX standards. The whole chassis is a combination of tempered glass and galvanized steel, and the thickness of the whole machine is up to 1.2mm. The chassis has a boxy design with panels complemented by elegant geometric patterns for a very modern look. It should be noted that although there are 5 fan slots reserved for this case, there is no fan included with the box, and players need to purchase them additionally.
 
Although the Inwin chassis is very different, and the air duct is also different, all of them have heat dissipation problems, and players also laugh at calling their chassis "big stuffy tanks", so it is recommended to use a reasonable back line to increase the number of fans in the case to create a smooth environment for the air duct.
