Can you return/replace it? If you can then there is this thermaltake with similar specs which I have been thinking about for myself. Has grilled front with dust filter so no concerns about airflow.

If you can't then personally I would look into seeing if you can't remove that acrylic panel at the front and remount it again but with a spacer so it is further out so it lets more air in around the sides. I am sure that would probably be enough to keep the case cool... may not look quite so nice with the front sticking out further, but if you search your local DIY store you should be able to find some kind of spacer or self-adhesive mounts that you can adapt.
Its hard to tell from photos how that acrylic plate is attached. But with a little care and creativity I would have thought you could do something reasonable... depends whether you are confident doing that. I know it isn't attached the same but this guy came up with a similar solution to a Walmart gaming PC here:
