InWin is one of the oldest manufacturers of PC cases and power supply units. The company was founded in 1985 and they recently celebrated their 35th anniversary. Unlike most other companies, InWin has remained almost exclusively focused on the design and marketing of PC cases, AIO's and PSUs rather than trying to diversify into other areas of the market. Today InWin is offering one of the most comprehensive selections of cases, ranging from low-cost towers to entirely unique designs. Well, we continue our momentum with this time, the In Win 315 test! The InWin 315 case is designed to become the basis of a gaming-grade desktop computer with an unusual design. As a reminder, this model is based on the 303 chassis. However, there are some differences, especially in the design and materials. On this version, we have a front panel and an upper part split in two combining aluminum and tempered glass creating an eye-catching contrast in appearance.
