I recently purchased Adaptec raid controller from AscendTech through their eBay store. The product is just as I was hoping. It works amazing. Was informed by a friend to make sure to keep it cool because they get hot. I have a side case fan blowing on it and haven't had any problems with overheating. It worked right out of the box for my unraid setup as well. I look to be purchasing another one of these cards soon and it will be from AscendTech.
