Moving inside the case we find some interesting features. Only one of the side panels is removable (the other is riveted in place), while the CPU socket is located at the bottom of the motherboard. There is no front case fan; case cooling is handled by a single rear bottom case fan in conjunction with a side panel having an ~120mm area above the CPU that is punched full of holes so that it resembles the old wire mesh fan grill covers. Although this is a somewhat unusual arrangement its lack of extra case fans means it is quiet enough to be used as a HTPC IMO and works plenty well enough to cool the 45W Sempron CPU that resides on the ASUS board. The power supply leads on what I believe to be a 250W unit (HP Customer Card model number spec sheet) could be a little longer as things are a little snug but manageable. There are also a few other misc air intake holes spread around seemingly randomly on the De-Branded HP Sempron case.
