A peek at the air intake on this door shows us that there is, in fact, quite a lot of ventilation capacity here. This is because Corsair has added support for – surprise – yet more radiators and/or fans behind both side doors. Yes, both.

A look at the power supply area inside the case. Remember, your power supply goes on its side in this beast, and I find myself somewhat wishing that for the money it costs to get one of these, Corsair had added something to keep you from scraping up the power supply on those braces in there. But that’s a minor nitpick – I’m not too overly concerned about that.

Down at the bottom of the shot, you can see two mysterious looking brackets bolted to the case bottom. Wait, let me get you a better look…

A red arrow, so you can see what I’m talking about. These are the rails with which you mount fans and radiators on this side. They’re stowed, here, because of the drive cages being present. You can’t use the drive cages and the radiator brackets at the same time.

Well… you might be able to use them and mount the drive cages to them so that the access is on the other side, instead, and removing the left side set of brackets, but I’m not testing that out today.

As is fitting for a super tower case, the motherboard space is gargantuan. This will take mini ITX, of course, but why the hell would you buy a case this humongous for such a weenie of a mobo? No, this thing is begging for EATX, HPTX, or XL-ATX. All of which Corsair claims are supported. And you can remove every last standoff, in case your board has no hole where some of the standoffs are. Believe it or not, that can actually be a problem with some cases that don’t have removable standoffs, instead of assuming you’re just going to throw a normal ATX mobo in there.

Spoiler alert – not every mobo conforms to that. Especially server mobos. When I was researching my existing cases, I quickly found out some of them couldn’t take the Supermicro boards I was looking at, even though they had the space. Reason? Non-removable standoffs.

In other words… thank. You. Corsair. You beautiful people, you.

A look at the expansion slots from inside. Here, I’ve got a beef with Corsair. You cannot access these thumbscrews with any straight screwdriver – you have to use the right angle one they give you. Why? Because the bezel blocks access. A case that costs this much and you can’t do some better kind of tool-less access, Corsair? Like the latch system, InWin used on the Dragon Rider, perhaps? Yes, I know that would make the case cost more, but at this point why not just go ahead and do it?

I have video cards that this is going to be an issue for, I just know it. Some of them, you can’t reach the thumbscrews because of the big brackets on those cards, so you have to start them with a screwdriver. Good luck with that on this case.

Our tour of the skyscraper now reaches the optical drive bays. There are four, all tool-less. To pop the front panel covers out, you need to reach in from the back and disengage the clips on each side.

Which then gives you this view on the front. I reckon a lot of people might complain about the fact that this breaks up the nice clean lines of the case, but you know what? Just don’t install an optical, Mr. Picky. Do you really need one here in 2016?

I’m going to drop my Blu-Ray writer in here, but I don’t know why I’m bothering. It rarely gets used for anything now.
