Introduction

GMC are a Korean manufacturer of PC cases and they are continuously trying to design innovative and functional products for enthusiasts who would like to have something a little different. Today we will take a look at one of their latest creations, the R-3 ‘Corona’. The R-3 is a tower case designed to fit a standard ATX system but with the minimum possible dimensions, making it considerably smaller than any standard ATX case out there. Of course such a design has downsides as well as advantages which we will examine in this review.

Packaging and Bundle

The R-3 Corona is supplied in such a small cardboard box you will find it hard to believe there is an ATX case inside. The artwork is minimal but it feels sturdy enough and the case is held by two thick Styrofoam pieces providing ample protection during transport. The bundle is very basic; a plastic bag with the necessary screws, an extension slot cover and a minimalistic manual.
