Your Honor: This mean a air purifier, and thus a more expensive electricity bill!

The original ATX design didn't expect a power supply at the bottom of the computer chassis, did it? Not even BTX (or CTX?) expected that, did it? I guess I should stop thinking about these chassis. -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

It is a good design for gaming cases that can then mount an exhaust fan on the top of the case.

Need to read the manual of the chassis to confirm your statement... -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

Could you name one? Try looking at the PC cases. The PSU (obviously?) isn't mounted so the intake fan is blocked, there is a gap for air to get in. -- SteveH |
