Given the restrictive flow in that case, I would probably have gone for the pressure optimized fans over the airflow optimized fans.
Ah bugger daveip unfortunately theyre already dispatched. I can't imagine the difference will be significant enough to merit returning the ULNs immediately.
Yeah, I'm really surprised the tiny Noctua cools it so well. I'd be really tempted to get this case if it didn't need a SFX PSU...
Yep the case's biggest downside is the very small range and wattage available in the PSUs. Hopefully there will be more soon such as the SST-SX600-G 600W one from Silverstone.
