OCC has published a review on the Antec Sonata Proto
Overall, I am definitely pleased with what Antec has supplied with the Sonata Proto. It is sturdy, clean looking, performs well and is quiet for sure. For a sub $80 case, I wouldn't say it is an absolute bargain, but absolutely worthy of ownership if a user is looking for a case that is sleek and stylish yet quiet case without all the lights and windows.Antec Sonata Proto Review
