I've been looking into this a bit more as of late just to see where its at since the posting. Product support is still pretty slim but there are a few nice items. For example, SilverStone not only made a case with the ESA circut built in but also offers a bay device (known as the "Commander") to pretty much convert any case to ESA capable. Just need 1 5.25" bay open. Prices I've seen are around $50 for their unit.
While the structure is all set up each company has to develope how ESA is used for their product. The trend in cases so far has been to have 5 or so 12v fan connection with some able to control fan speed. Only up to a .5 amp fan though
So no Ultra Kaze. Others simply just use it as a reporting tool. Some also add a status LED for Power \ Water Cooling \ and Failure (ie: over heating). However CoolerMaster stuck those LEDs inside the case. Why I have no idea, as it was ment to be a way to report failures while in full screen mode and not interupt you. It comman sofar to see a $50 increase in prices on cases for it. Like I said though... sometimes you dont get much for the price hike.
I believe if ESA is really going to take off either some company is going to have to send some $$$ on better development or its going to left to the old grassroot modders that invent creative ways to adjust poorly done design work. If a company like ASUS, whos has their fingers in many different pc components, came up with a slick package they could corner the market pretty easy for awhile. Why buy an EVGA or XFX ESA board if they offer better functions. Or even a mac or Intel for that matter... I wonder if LCD Studio or another similar program could pull info from ESA to be displayed on an LCD?
As far as product support here is what I've found sofar:Thermaltake:SilverStone:CoolerMaster:PC Power & Cooling:EVGAXFXTaganCoolITZotac
