Chassis Airflow
Date Issued: 20th Oct 2008

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 3 out of 5 by from Cost a lot's not great. Its big and heavy but it should be its supertower but there's some things I dont like. Paint strips off very easily, its not rather sturdy, feels like really cheap metal. It should cost half of the price not more than 300£

Rated 3 out of 5 by from Good, but not great Case is *not* set up to handle SSI-EEB motherboards, which I find unconscionable in such an expensive case. Lacks a certain amount of flexibility. I had to modify the case in order to find room for a dual-loop water cooling system. Also quality control could be better, mine was delivered with a malfunctioning front filter latch. Too many pop-rivets, too much plastic. All in all a decent case, but not really worth its price, at least for dual-processor systems.

Rated 5 out of 5 by from The ultimate in space case if you want a case that has you wondering "what else can i fit in here, it looks kinda empty" then this is the case for you! this case makes even large cases look small, i went from an antec 1200 and that now looks tiny, there is enough hard drive enclousures to house enough data for any server requierment (although the doors and sleds on the drive bays are a tad flimsy in my oppinion)... the basement area is very accomodating for quite a lot of radiators although the front fan does need to be removed to get the longer rads in... the front disc drive bay indentations are an aquierred taste but if ur side on mounting the case on a desk to look through the window like i have then u dont even see it. i do reccoment scan getting the basement floor plate as this really does clean up the case to no end as i have just made one and it looks very nice!

Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from truly massive This is truly a massive case with loads of great features and potential for creating a amazing system.

Rated 4 out of 5 by from 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

Rated 5 out of 5 by from 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
