Um... If it's 2007, then you might have a problem with the fonts. For some reason they were hard for me to read. Also, if you're running RAID, i don't think it's gonna be able to utilize it out of the box.
I don't mean to change the topic or say Mandriva is bad (cuz it isn't), but Fedora 7 is a great too, almost a complete OS, and it can RAID right out of the box.
