In Win Unveils S-Frame, Unique Single-piece Chassis
 

No, it's not a winshield sunshade an In Win employee brought to the show floor. It's the company's unique new single-piece chassis, made by folding a single piece of anodized aluminium, with holes punched at the right places, so you could screw in your motherboard, add-on cards, drives, and power supply. Since the case is cast out of a 3 mm-thick sheet, there's no chance of your 3 kg high-end PSU, 700 g hard drive, or 1 kg graphics card bending it in any way. In Win unveiled three kinds of single-piece chassis, the first one being tower-type, next a flat-out open type, and a third, slanted open type, pictured below.
