So i've just purchased a new motherboard (Asus Z97-AR), CPU (i5 4690K) and 16GB DDR3 ram. I want to install this in my old "Antec 300". Alot of people tell me that i should buy a new chassi aswell since mine is so old. The thing is though, that i really like my "Antec 300" despite it's age and the fact that there is no real cable management option to talk about. Is it really such a bad idea to install new components in a chassi this old? I mean, it has two fans already plus one that i installed myself when i bought it back in 2008 I'm also planning to install one more fan at the front to keep my Noctua S12-1200 company. So from a cooling perspective it can't be that bad, despite what people say.
