The In Win 303 Case Review: Minimalist ATX with Tempered Glass for $93

The Exterior of the In Win 303

The In Win 303 visually is very simple, perhaps even excessively minimalistic. All of the case’s panels are metal and only the side panels are removable. The front and top panel of the case are entirely flat, with just the I/O ports, buttons and an illuminated panel with the company’s logo at the front of the case. We received the white version of the 303 that has white exterior metal panels, with the exception of the smoked tempered glass door (real glass, not acrylic) left side panel. The paint is very well applied. Note however that the white paint of the 303 is not perfect white or snow white, but leans slightly towards the floral white hue.

11.2 oz soda can added as a size reference.

Measuring 50 cm tall, 21.5 cm wide and 48 cm deep (19.7 × 8.5 × 18.9 in), the In Win 303 is not small for an ATX tower case. It has a volume of 51.6 liters, almost identical to that of an advanced ATX case but with optical drive bays, the Corsair 450D (also 51.6 liters). It is larger than the Zalman Z9 Neo (48.4 liters) and NZXT S340 (38.4 liters), which are relatively low-cost ATX tower cases, but it also is very heavy, tipping the scales at 11.2 kg, making it at least 50% heavier than typical ATX cases. A portion of that will be the glass panel.

The front I/O ports and buttons can be found across the right side of the front panel. A large square Power On button can be seen at the top corner of the front panel, followed by a small square reset button. An illuminated panel with the company logo separates the I/O ports from the two buttons. Two USB 2.0 ports, 3.5 mm audio jacks and two USB 3.0 ports can be seen in line under the illuminated panel. These six ports also have illuminated surrounds that will stay constantly lit as long as the system is powered on.

A look at the rear of the In Win 303 case hints that the interior design will be more or less atypical. The system area is at the bottom of the case and the PSU compartment is above it, resembling the classic ATX configuration. However, the PSU is mounted vertically, drawing air in from the right side panel of the case. One slot for a 120 mm fan can also be seen.

The bottom of the case serves as its main air intake. The clearance between the case and the surface is barely adequate, with the 303 standing on two large but short rectangular feet. A large nylon filters covers the entire intake, which can be removed by pulling it from the side of the case. We found this to be an excellent design choice, as the filter can be easily accessed from the side of the case. Considering the length of these filters, removal from the rear of the case is typically problematic and inconvenient, making this design a bit nicer.
