InWin 103 RGB Tempered Glass Mid-Tower ATX Case - Black- 7x Expansion Slots - Supports 2x 3.5" & 2x 2.5" Drive Bays 1 Year Warranty




Note: The PSU portrayed in the photos is NOT included. The IN WIN 103 represents a stylish Midi-Tower that is also ingeniously designed. Manufactured using the highest quality steel, and equipped with an expansive tinted tempered glass side window, the IN WIN 103 is perfect for high-end gaming systems that use motherboards up to and including the ATX form factor. The other advantage that this case brings with it is the hardware presentation: components will certainly look their best in this case thanks to the premium build quality we have come to expect from IN WIN.

The IN WIN 103 combines modern aesthetics with an attractive premium aesthetic. It has been constructed primarily from high-quality steel and distinguishes itself from the competition by means of a large side window in tinted tempered glass. Given IN WIN's reputation for innovation, it comes as little surprise to find they have included a clever kind of 'grip' towards the upper edge that enables users to open the case without requiring tools. The overall look of the case is defined by its surprising variety of designer additions, such as the way in which the case's interior and exterior are coordinated in white to lend the Midi-Tower an elegant style. The use of vertical and diagonal lines emphasises this yet further. But one particular highlight worthy of mention is the addressable-RGB IN WIN logo. The lighting can be controlled using a compatible motherboard with software like ASUS's Aura Sync, Gigabyte's RGB Fusion, MSI's Mystic Light Sync or ASRock's Polychrome Sync. The top of the 103 Midi-Towers is where users will find the I/O panel that includes a power button, two USB 3.0 jacks and a 3,5mm jack for HD Audio-in and -out.

Of course the interior of the case holds a few surprises as well. For example, users install their PSU in the top of the case, and this is located behind a perforated cover for airflow. As a result, the motherboard is then installed beneath it to lend your hardware a seriously sleek and professional look. A convenient support for graphics cards likewise comes included, a thoughtful addition since high-end graphics cards can be surprisingly heavy these days. That aside, the interior also offers adequate space for ATX-, Micro-ATX-, and Mini-ITX motherboards, CPU coolers up to 160 mm tall, graphics cards 421 mm long and PSUs up to 200 mm long.


The cooling design of the IN WIN 103 is anything but standard. The theory is that cool air is pulled in from the front and the bottom of the case, then exhausted from the back. The bottom of the case allows for a maximum of three 120 mm fans or one 360 mm radiator. The rear supports one 120 mm fan or radiator of the same size. A special feature of the case's overall cooling is the fact that it supports vertical mounting for up to two 120 mm fans or one 240 mm radiator to the right of the motherboard. It is here that warm air is pulled outwards through a honeycomb structure in the right side. In order for users to enjoy as much freedom as possible when it comes to their choice of case cooling options, IN WIN does not include any fans as standard.

IN WIN has naturally taken care to provide users with plenty of hard drive bays. The top section, next to the PSU, supports two brackets for installing 3,5" hard drives. Additionally, the rear of the motherboard tray provides brackets for two further 2,5" hard drives. One thing the IN WIN 103 certainly can't be said to be lacking in is the range of storage options!
