Well, folks, it's finally happened. Someone sent me a refrigerator to review. I mean, that's what it has to be, right? What else comes in a box this big? Corsair's now shilling fridges, and their first new fridge is called the Obsidian 900D.

I love the fact that the box is asking me what I'm going to do with all this room. Stuff it full of soda, that's what. I've got a regular fridge for all the meats and veggies, so it's good to have a special one just for my sugar and caffeine collection.

Yeah. It's a fridge, all right. That stuff about designing a dream PC, state of the art liquid cooling, and file servers is just a red herring; meant to distract the competition at Whirlpool while Corsair gains market share. I'm six and a half feet tall... no computer case shipping box comes up most of the way to my hip height. It's a damn fridge.

The deception continues on this side of the box. I see drawings of fans, hard drive cages, and doors. It says under "contents" that there's a super tower PC case in here and a system builder's guide, but I'm sure they really mean "ice maker" and "defrosting instructions."

Huh... you know what? I'm starting to think there really is a computer case in this box. Let me just do up a table here with the specifications...

Holy chunkey monkey - 690mm tall? Ok, that's just ridiculous. But there are people who do need gobs of space to build their computers when not just any case will do the job. I should know, I built one of them recently. Let me tell you something, people... when an Inwin GROne is not enough case for you, it's time to just go big or go home. My new main rig build was enough to make that big boy seem cramped, and I'm looking forward to seeing what Corsair brings to the table with this beast.

Speaking of bringing things to tables, it turns out the box is about the same height as my photography table, which is 29 inches off the floor. It's nice to see the case well protected in there by foam, because after spending what this case costs, I don't think too many of you would be pleased if it came out of there with damage.

There is no manual included with the case - just a quick start guide and warranty info sheet. To be fair, there's not a lot about this case that's not intuitive.

Pfft. Not a fridge. It's the gotdang Sears Tower. Hold on a sec while I go up to the observation deck with my DSLR.

Good news! I can see down into Montana from the top of this thing!

Let me just get all that protective plastic off this monster so we can see it properly. By the way, see that tripod in the reflection? First time I've had to fully extend it for a computer case. It's not a short tripod, I just make it look that way.

Well, that's just one sexy looking view, right there. Like the 750D, only friggin' huge.

I'm going to answer the obvious question right away - yes, the side panels do interchange with each other. Some of you don't want windows where you can see them... I am one of those people, ever since I bought a motherboard with a blindingly bright flashing green LED that can't be turned off.

See that gap around the lower door, there? That's actually a well concealed air vent, hinting at some of the cooling capabilities of this case. There's a matching one on the other side.
