Ok, so you are tired of hearing about the window already, but I think it is the one thing missing that would make the 600T the ultimate in mid tower chassis designs to this point. I got a lot of the features that I loved in the 800D I used for my main rig. Excellent management of the wires, even better access for CPU back plates than the 700 and 800D offered, and that super clean finished look from the inside. Now it does take some styling and design cues from Cooler Master cases we have already seen, but I think that is directly Corsairs intention with this chassis.
Taking that a step further; head to head I will cover a few features. Let's start at the top. Both have a 200mm LED fan, both have access for a dual radiator, and both have "handles" built into the top plastic, just in a different way. Taking that one step further, the 600T feels more structurally sound when actually carrying the chassis from the top, and I haven't even touched on the removable panel to hide fans. Inside the chassis, the 600T offers much better features in wire management, all black wiring, and both have removable hard drive racks, but the 600T's version is much easier to remove. Moving to the way the chassis is supported, the 600T is more stable and you don't risk breaking the "duck feet" of the Sniper. Lastly, there is the physical appearance. The 600T is more refined and less industrial looking, leaving the 600T with a clear win over its competition in my eyes.
Of course, if you are going to build a chassis that competes directly with another big name already on the list, you are going to have to do two things. Offer me a superior product, and price the chassis well enough to make me change my mind. Corsair has definitely won me over with the superior implementation of features, as well as the more solid "feel" of the chassis. So that leaves us with the pricing. The Sniper can be found for around $140 plus another $10 to ship it, so we are at $150 to get one to your door. Now, with what you have seen in the photos and what I just mentioned in the comparison, the 600T offers more out of the box. That said, I think the $159.99 via Newegg.com is more than a reasonable price. Right now the shipping at Newegg is a bit of a deal breaker, but with some selective shopping, you are bound to find a better shipped pricing. I really think Corsair is going to take a large percentage of the mid tower market with this fine specimen.
