From late 2004/early 2005? This one's funky. The front 80mm fans have been updated to a single 120mm, at the expense of the fan controller and 1x 3.5" bay. There is also a two piece duct for the fan on the motherboard tray which is intended to be used as an intake and feed air to the CPU cooler (the black grill is glued in place), and along with that there's a blower fan exhaust mounted over where a graphics card would be. There's also a fan in the top, now secured with screws instead of pins (the holes are countersunk to accomodate the screws so this is intentional). I've no idea how effective this airflow arrangement would be but I'm guessing it probably isn't great! The front panel I/O is now updated to include audio in/out and Firewire (remember Firewire?!).
