Very nice case, you will be happy.
Although they made some unnecessary changes and called it the P183. :P
It got better ventilation :]
Putting it all together tomorrow I hope.
The only plus in the ventilation is having holes in the dvd drive/optical drive areas. Otherwise the bigger holes on the sides and the holes on the front were not needed. And the holes on the front make the case look a bit ugly in my opinion. Just having holes on the sides is plenty. Having the smaller slits looks better in my opinion.
The fan placement in the bottom chamber is the best part. They should have done this from the beginning. They probably didn't just so they have "upgrades" in newer models.
