Standing tall at 16.7-inches the Circle Bloom is a full sized ATX cabinet with a front bezel door. The door is magnetic and hence is conveniently held shut. Both USB ports and line-in and line-out jacks are placed towards the sides rather than having them placed behind the bezel door. This nullifies the need to keep the door open when connecting external devices via the front ports.

Even though the Bloom is a full sized ATX cabinet, graphics cards such as the Nvidia 260 will not fit, since the drive bays get in the way. Adding more storage shouldn't be a problem since the Circle Bloom has a total of three 5.25-inch and six 3.5-inch bays. To enhance air circulation both the front and rear are fit with 80 mm fans. While the front can accommodate a 120 mm fan, the rear has support for an additional 80 mm.
