Conclusion:
For a reasonable price, the GMC R-2 Toast is a unique looking case available in a great selection of bright and lively colours. The design certainly is different than most computer cases, but for non-power users who don't require a lot of bay components or extreme cooling, it would be a great case choice.

Pros:
Unique and very cool looking design
Compact size for being a full-ATX, mid-tower case
Optical drive mounting is unique; a good centerpiece
Lots of vivid colour options available

Cons:
Lacks any external 3.5" or 5.25" bays (for things like card readers or bay buses)
Cooling with 120mm fans would be quieter and more efficient
