You know, it's really impossible to anticipate every type of question when doing a review. I look back at it, and could have done some things differently and added more data, shots of things, but I don't have the time. I just try to present the facts first, then add my own opinions. It's ultimately your own choice.
I knew CM Sniper comparisons would surface, but felt it wasn't fair to Corsair to bring it up in the review. The top fan control knob is a huge similarity, but otherwise entirely different cases. I figured I would get this out of the way now. I completely dismantled T2's CM Sniper last year
HERE It has overall cheaper quality molded plastic. The internal HD trays and tool-less latches in the Sniper are more susceptible to breaking. I busted the tool-less PCI releases not once, but twice! and I'm not hard on cases. The Sniper's top fan control is flimsy compared to 600T. The Sniper's MB tray is smaller, lacks cable the big holes. It does have perforated side panel and space for tucking wires, but only because of it's bulges. The Sniper has more fan options. It is cheaper than 600T if you shop around, $40 - $50 less... You either love or hate it's industrial style exterior... I do think the 600T's minimalistic exterior will have more longevity for most people's tastes.
Here are the fan specs I could find for each case. There is no proof anywhere that these are 100% accurate.
