Great guide! I got stuck at the Mobo tray, I knew the black screws were involved but couldn't get it with out help. Thanks!

Fans can be removed with board tray, otherwise they're getting pulled off their rubber isolating feet. Once out with the mobo, the fans slide off the board tray with their plastic shoes attached.
