Gigabyte haven't let me down and I've had 4 cards from them so far, even when one broke the RMA was simple enough and I didn't have to register anything as RMA's are based on the products serial number. I can guarantee in a short while they will release a windforce fan edition which is just like an accellero with two or three fans but unlike the accellero it will only take up two PCI slots instead of 3.
I can guarantee this reference design Gigabyte will serve you well
Also forgot to say, whether you put an Accelero on or with any fan based card that doesn't external exhaust, you will need a whole pci slot gap between each card so that the cards have room to breath and temps don't sky rocket.
