The power supply is the same dimensions but uses 150 watts (Jasper) instead of 175 (Falcon) or 203 (Xenon/Zephyr) now, and the "vaccum" is an air duct, the fans are in the back. So anyway, same size motherboard in every console. Screws are in the same place, same exact case (only differfence is the HDMI port). Also, you can use a 203 watt PSU on any revision, but the 175 watt only on Falcon/Jasper, and 175 watt only on Jasper.
