Actually, It's missing 3, as best as I can tell. I found the rear fan, 
it has a 3-pin connector. There's also a rear power supply fan, it also 
has a 3-pin connector. Now, I saw that some of the later models had 
hard disk tray fans, but I couldn't find a connector for them. I'm sure 
that they're there somewhere.

Also, it seems that there's only a spot for one fan on one of the 
trays. I can only assume that this is normal...
