Not only do x86 quad cores not exist, I'm pretty sure this case was made before Phenom came out anyway. It doesn't have an air duct, contrary to what it says on the box. It comes with a PSU with a total of 31A on the 12v, that sure is enough for quad SLI. I don't even know what the <39c thermal standard means. And yes, this case is SLI ready, I don't know a single case that isn't, but this one is, and that's all that matters. And yes, you did read that right, this case also supports SATA, that's right SATA! Because there's a physical difference between the case of a SATA and IDE drive of course. What these people will put on the box to lure in newbies is amazing.
