I was in the same boat a while ago and decided to go with the 590 for the cable management. Now I wish I'd gone with the Antec instead, the 590 I got is very cheaply built. Stand-off holes weren't drilled correctly, panels are thin and flimsy, don't line up with the case correctly, and one of them is warped so it doesn't slide back into place as easily as it should. Happens to be the left panel that grants access to the internals too, go figure. Plastic case feet instead of rubber, no reset button. And the fact that I paid about $20 more than I could've gotten the 300 for at the time just adds insult to injury. I've had mostly Antec cases before so I know they're quality, this was my first CM case and it's a piece of crap.
