I'd recommend aftermarket filters if you're REALLY going to use them. Average gamer though, not as much. You have to open up your case and clean it out about once a year anyhow, so filters aren't THAT crucial. HardOCP is probably an overclocking website, am I correct? Those guys are enthusiasts, and they fall into a different bracket alltogether.
I'd use the filters that came with it. My Antec DF-30 has built in filters that seemed BS, but after about three months of use since the last clean, I can tell you that they WORK. Don't be afraid to use the stock filters, aftermarket filters may very well hamper airflow and increase noise levels.
