  7. Conclusion

This is the second chassis I am reviewing from Antec. The first one made a very good impression on me, but I always believed that if one can make a really good low-cost case, they can provide a great value in higher cost cases as well.


The rear section of the Antec One S3’spackaging is pretty much the same what Corsair does- having an illustration of the removable bits and pieces shown, along with the specification in multiple languages.
As expected from cases belonging to this price range, the case is protected by 2 blocks of Styrofoam and a plastic wrapping.

  1. after adding $20 more you get 300R from corsair a much superior case. bitfenix and caselabs have good cases too. antec is late to the party and this is the party they should be an early bird…
