2 out of 5 eggsHeavy =/= Sturdy, But Still.

Pros: Sleek design, plenty of space for mid-sized builds, and a few nice options on top and inside of the case. Arrived well-packaged and undamaged; Props to UPS.

Cons: Thin metal/light-weight, questionable structural stability, and more plastic parts than I was expecting. Window-side panel was flimsy and barely holds on if its two thumb-screws aren't fastened. And last, the internal HDD bays weren't secured: when I opened the case to examine the interior, it became clear that the compartments inside were not to the well-fastened to the bottom of the case. This didn't seem to be a result of shipping either; I applied slight pressure to each of the bays and they held, but were not stable.

Other Thoughts: I'd say it should run for about half it's current price just because it's clear some design went into it, but I would have really appreciated a heavier/more stable box. Up front, I've been using the Antec1200 for my last two builds and have been used to that really sturdy feel, so maybe it just takes some adjusting, but I'm returning this case; I'll definitely be sure to go see/feel a demo of my next case before just ordering it off the internet.

5 out of 5 eggsBest case I've had

Pros: This is an extremely functional case and even though it looks relatively simple, my build looks beautiful with this case. The huge side window really shows off the wonderful cable management and my components.

I've never enjoyed a build as much as this using this case. It made putting my gaming PC together a very enjoyable experience, which was a first for me.

Lots of filters, including one on the vent on the bottom for the power supply which allowed me to mount PSU facing down which was unexpected and great. Two big fans drawing cool air in. Tons of space on top to mount my Corsair H105 radiator and fans. I like how the front clicks open to reveal the fans and filter. The filters are so easy to remove (a far cry from my previous Antec case). The magnetic filter cover on the top is awesome and a great idea. The SSD mounting system on the opposite side of the case looks very streamlined and was very simple. It allowed me to remove the HDD cages completely (which took two seconds to do) and allow for even better airflow and more openness. USB 3.0 ports on the front have been great and are lightning fast. Love the rubber passthroughs for the cable management. Just can't say enough good things about this case. It's just well thought out.

Cons: Doesn't have a lot of bling to it but this could be a pro too. It accentuates what's going on through the side window more, and it just looks so clean.

Other Thoughts: By far the best case I've owned. Very well thought out and made building my computer that much more enjoyable. It looks great, feels very sturdy, is quiet, and my temps are nice and cool.

1 out of 5 eggsCorsair Obsidian 750D Black ATX Full Tower Computer Case

Pros: NONE

Cons: What a horrible delivery service the box arrived with a massive hole in the side. They tried saying it should be fine after pulling the product out of the box the whole side of it was shattered. Called customer service for a refund and they said it would have to wait until the funds were credited to my account then reorder the product. WARNING DO NOT USE SHIPPING FROM UTRACK THEY ARE HORRIBLE

5 out of 5 eggsOh man this case.

Pros: Never having owned anything from corsair personally, I must say I have been missing out. Not just on the craftsmanship side of it, but the Support is far superior to anything I have yet to witness.

Cons: My case came with a dent on one side, and a scratch on the other, But thanks to Corsairs insanely fast reacting customer service reps, My jaw dropped further than when Rick Grimes bit that guys neck off.

Other Thoughts: The case itself is astounding. Mine is currently at the paintshop having the Milky Way airbrushed onto the solid side of it. and I am thinking of having the SDF1 either 3D printed for the side, or etched into some plexiglass.

The rad placement, and sopace availability is top nothc for the cost of the case. I really honestly dont think there is better for the money, and I have always avoided everything corsair because I "THOUGHT" someone else always had something that did the same for cheaper.

Once again, I am ASTOUNDED by the quality of this case.

5 out of 5 eggsAnother Instant Classic

Pros: Classy and interesting, like all Obsidian cases. Sized just right, large without being overpowering like the 800D/900D, and priced below the 650D (see reason why below). Well laid out, with movable 3.5/2.5 drive cages and great cable management. I feel that my system is breathing a lot easier, it's running cooler than my old case and a lot quieter, with fewer fans. The AF140Ls move a lot of air quietly, and provide direct airflow to graphics cards (with drive cages configured as shipped). I was going to wait for the 760T to become available, but now I'm glad I didn't.

Cons: This case feels a bit flimsier than some older Corsair cases, stamped from thinner steel. I also felt like the drive cages were flimsy, and they arrived slightly out-of-square. Not really a problem unless you're hanging both of them from the ODD cage (as I did to fit a radiator in the bottom), then they swing around too much. I made a bracket to attach the bottom cage to an unused motherboard standoff, and now it doesn't swing around like a pendulum. They could' have made the cages a lot sturdier by using slightly thicker steel in this important area; these are like something out of a much cheaper case. That's how they managed to price this below the older, similar-sized 650D, by using thinner steel all around and thumbscrews instead of latches on the side panels. Still a great case, just don't drop it or it might end up diamond-shaped.

Other Thoughts: Best looking case for the money, even if they had to cut a few corners.

5 out of 5 eggsBeautiful, simple.

Pros: First off, let me say this case is beautiful. It doesn't look like it might transform and run away, yet still has a side window to appreciate my internals with.
Secondly this case has a ton of room on the inside. I was able to route all my cables (including the 24 pin connector) behind the motherboard. Along with a corsair modular power supply I was able to get wonderful cable management.
Relating to the last bit, I was also able to fit a metric ton of fans in this bad boy. I purchased myself some of the AF140s (8 of them to be exact) and was able to fit them inside here with enough room for 3-4 more. Later down the road I plan on using the massive amounts of room in this case to do some extensive custom water cooling and I have no doubt all of it will fit.
Lastly this case will bend to your needs, it comes with two 3.5" HDD cages that can both be removed or added in either mounted to the bottom of the case or hanging from the 5.25" bays as well as enough room for as many SSDs as I could afford! I personally got an adapter to put my 3.5" drive in the 5.25" bay so I have plenty of room in there.

There are plenty more pros to this case but I think this about covers it.

Cons: As great as this case is there still were some gripes.

First off the HDD sleds are a bit flimsy, I broke one of them while pulling them out, granted I was pulling it out a little more forceful than I should have.The SSD holders that mount to the back are also pretty weak as I broke the clips in one just by removing it. This might be exclusive to me however.
My second con is there isn't a magnetic dust filter for the entire bottom included. This would have really put it into a luxury quality for me.

Even with these cons I can't knock off an egg.

Other Thoughts: All in all this case is 100% a luxury case. This thing looks gorgeous and displays my internals like a piece of art. It has given me a taste for the finer things, and those finer things come from corsair. This was my first corsair purchase and it turned me onto the other products. Now if only I could find a way to make my internals always look as good as my case! ;)

5 out of 5 eggsTop Drawer

Pros: Ample room for whatever you can think of putting in it, even 3 or more beefy video cards.
Tool less mounts for drives and expansion cards.
Excellent cable management, ample room behind the motherboard for wires and cables with rubber pass throughs.
Bottom mounted PSU
HHD cages can be stacked or side by side
magnetic mesh cover on the top with room for 3 120-140mm fans, room for two more bottom mounted fans.
Comes with 3 quiet 140mm fans, two front intake and one rear exhaust.
Overall sleek understated elegance, this case looks very nice.
Large window, and I like that there is no fan in the window.
Solid construction, very sturdy and stable.
I really cannot think of anything to nit pick about, a lot of thought obviously went into designing this case. If I had to take issue with something I suppose it could be cheaper, but for what you get I am very happy.
This case really is large, make sure you have room for it.

Cons: seriously?
