It appears to be more of an add on than anything related to a full system design. Frankly a Cooler Master case like the HAF would do as well
if not better than that silverstone....
ESA was put forth in 2007... and as you might have gathered from googling, it didn't really take off. One on hand it's system monitoring, which
is already quite do-able. Asus software that comes on their laptops and mobos does a lot of this. On the other I dread that it was a gross over simplification
of the heating, cooling, and overclocking skills.
Nvidia invented the stuff, so the main boards that used any form of ESA were from them. So you can cross out a lot of prospective mobos right there.
Plus... while the ESA stuff is still in their Nvida System Tools, and seems to be part of their video cards as recent as the GTX460... mobo wise no one really cares.
A good article on the matter -
