I sort of have one. I order the 580W one but about 10mins after ordering it I realized (from some pics on a review site) that it doesn't have the 8pin connector my mobo needs (server connector) so I have to return. But from the site I've read they are the bomb! Best modular power supply out there, well the 580W, I don't know if the 480W are modular or not. check out Xoxide.com to order a 580W and just copy the name and paste it in google and add "review" at the end and you'll find some.
PS I got the blue one too, so upset I have return it and use a plain-jane one, but I want to have the maximum amount of power going to mobo, so I guess that's life.
