The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Rated 4.4 out of 5 by 10 reviewers.
Rated 5 out of 5 by Absolutely Fantastic Used to have a HAF-X and wanted an upgrade. Decided on the 900D and what can I say, the best case that I've ever built in (I used to be a systems builder for friends and maybe built in 30 or so cases). Its fantastic. The quality of the construction is second to none, the layout is perfect and I love the availability of add ons and mods. I'm considering getting a mid-plate for it however as you can get them online for fairly cheap and I think it would make it even better. But apart from that I think the overall case is just perfect for what I want. If you're in the market for a big case, look no further, this is in my opinion the best on the market! 04 May 2016
Rated 5 out of 5 by truly massive This is truly a massive case with loads of great features and potential for creating a amazing system. 20 July 2015
Rated 4 out of 5 by Awesome Case The case itself is amazing, huge amounts of space to play with. The cable management is fantastic. The airflow tests I have carried out, proves that Corsairs put quite a bit of thought into how the cooling would work. My only issue with the case is for a £300 case the build quality is lacking. The side panels don't come off very easily, my 1st attempt at getting them off made me think that there was a fault. But I can't see one. The top comes off easily enough, but getting it back on is a real pain. I feel quite let down by the quality. My old Cosmos S was amazing so was hoping for a similar build. Overall though I would recommend this case, as the liquid or air cooling options are immense. Plus its very pretty 18 January 2015
Rated 5 out of 5 by Great case Ordered this to replace my 800D what was starting to get a bit old, different in size is quite a bit. However it is well worth it just for the space for the cabling routing compared to the 800D. My only issues with the case is that it comes with three drive bay racks with only one Hot swap bay the case should have at lest two as standard. The Fans what come with the case the cables are a bit short corsair needs to look into fixing this, or providing some extensions due to the size of the case it makes it hard to connect them to your Motherboard. Also they lack 4pin connector. Only cosmetic issue was with the top of the case the panel is was very hard to remove and it looked to be bent in places. I will bug corsair about this when I have time. Moving all my hardware into this case was a lot more simpler than changing it around in my 800D mainly due to the space 19 October 2014
Rated 5 out of 5 by Huge doesn't cut it! 1st thing it it's size and weight. It is huge and heavy. Which is not a bad thing as you mite think. If you have spend a good amount of money one your pc. Want to know its safe! I have 3 young children they lean on it all the time it doesn't even wobble. I also have got rid of my pc deck as I only ever used it put my monitor on. Now it go on the case. Even with a gtx 780 classified in sli, it doesn't look crowded. Temps are good to out the box on air, even with stock cooler and overclocked. Can't wait see what happens when I get it on full liquid cooling. And with most corsair cases cable management is a dream and quick to do. On the down side there are a few niggles with the quality, the bottom radiator doors and main side panel, do not fit quite right. And when you install fans in the bottom the latch will not lock. Even with the niggles I love this case. You mite need to plan you room around the case, but your spending this sort of money on a case, you will want to show off hardware to, so who cares! 30 April 2014
Rated 4 out of 5 by Excellent Upgrade Case This case is excellent for a diy build, It Is so big you can put anything in it and still have room. Easy to work on,cable management is really simple with so much room at the rear of the case.Large tinted window with single button quick release lets you easily access the inside. Drive bay caddies are all modular and can be easily removed or repositioned to suit your needs. This case is huge so make sure you got the room for it before you buy it,and it is heavy even when empty,you wont want to be moving it around to much once you start putting things in it. The top cover can be hard/stiff to remove, Being such a big case you may want to think about getting some extension cables. Instructions for the case are are very basic,i had to go on you tube to find out where the lower radiator rails were,they were screwed to the bottom of the case. had to remove the drive caddies to get to them.but wasn't a problem. Overall a very smart looking case im glad i bought it, 28 March 2014
Rated 5 out of 5 by best thought out case ive ever owned very well put together and thought out. i have only one minor issue and that is there is no instruction sheet tell you how to move the 3.5" bays, but thats no big thing. top filter is i bit tricky to remove and the buttons to pop open the bottom panels seem a bit flimsy. but again only small daft things. i am very happy with it and i can see it giving me many years service. capacity to run multiple water cooling loops, which is going to be my next big purchase. and the extra depth on the back of the motherboard tray really helps with cable management. 29 November 2013
Rated 4 out of 5 by This product has really good features but... ... it lacks a quality feel to it as it arrived to me with one of the clips broken off which i had to repair myself. Also one of the rubber feet on the bottom came off as I was moving it. This said the case is a very big case and has some really nice features for any computer enthusiast wanting to start modding their computer to the max. 07 November 2013
