Before we dive into our final thoughts on the InWin Explorer, let's talk about price. At $140, it includes what is essentially a 3-pack of retail Luna 120 mm fans. That results in a case price of $110. In terms of pure material cost, that still feels rather expensive. Most of the parts are plastic; with both the side and top elements being identical, you are essentially getting two pairs of each. On top of that, you get a few steel components which are sturdy but don't push the envelope in terms of elaborate engineering. That leaves the clear glass panels, which are budget-oriented 3-mm panel that are equipped with plastic corner pieces to attach to the chassis. All this means you are clearly paying for the the unique look and experience.
That having been said, this is by no means a bad thing. The InWin Explorer in "Bone White" or "Justice White" looks different than your run of the mill mATX or ITX case. This is both a result of deliberate design and engineering, and the fact that you get to experience that whole IKEA feel of assembling it yourself. That aspect holds especially true for the Justice White version with all its different color elements, and the assembly of the InWin Explorer is indeed a fun and entertaining experience.
Looking at it purely in terms of functionality, features, and compatibility, the InWin Explorer does show some weaknesses. The interior feels very oversimplified with a near complete disregard for cable management, limited storage options, some odd screw-mount placement for both hard drives, and the ATX frame. The omission of cable hooks in the metal plates or the weird gap for the rear metal piece does stick out, and the simple ATX frame with its missing walls, where InWin could have placed additional storage mounts or cable hooks to bridge the gap from ceiling to floor, is simply unfortunate, speaking of the simplicity of the chassis from a functional standpoint.
All that makes the InWin Explorer the type of chassis a teenager could enjoy, as part of an air-cooled, somewhat compact gaming system parents built by employing adequate hardware and those ARGB elements of the Luna fans. That kind of target audience would be far more inclined to enjoy the colors, soft edges, gentle curves, and initial assembly experience, and thus the result of "having built something of their own." The InWin Explorer deserves recognition for the spirit of innovation even if it comes at a tangible cost both financially and functionally.
