The new model is very similar to its predecessor but the main difference is there's now room for a standard ATX power supply, whereas the original model required the use of a SFX PSU. The new Raven Z supports ATX PSUs with a maximum length of 150mm but SilverStone recommends not going above 140mm to avoid issues with the PSU connectors.
The availability of the new model is unknown but we do know it will cost $79.99.
