Product Overview The Obsidian 450D is the ideal blend of solid, refined good looks and high performance cooling. In front of the two AF140L intake fans is an easily removed aluminum mesh dust filter that provides extraordinary airflow directly to your graphics cards and CPU cooler. On top of the case is room for up to a 360mm radiator, a rarity in mid-towers.

Of course, it wouldn’t be a Corsair case without well-known, easy-to-use features like tool-free drive mounts for SSDs and 3.5” drives, optical drives, and excellent cable routing. Whether you’re looking for high airflow or potential for liquid cooling, the 450D has you covered. Features • Generous expansion room for building high-performance systems.
• Beautiful brushed aluminum fascia with mesh cutouts makes an elegant design statement.
• Full side panel window to view your components.
• Tool-free SSD, Hard Drive, and Optical Drive installation.
• Includes two AF140L intake fans, and a rear AF120L exhaust.
• Tool-free SSD cages hidden behind the motherboard tray.

Corsair Obsidian Series 450D High Airflow Mid-Tower Case is rated 4.5 out of 5 by 12.
Rated 5 out of 5 by from I very like this case I bought this case 5 month ago and what I can say. This Mid-Tower Case for me is great. Enough space inside like for one GPU, and Water Cooling system and looks very nice. I know that probably will be few people who will say that design is bad or something like that. In my opinion this is worth this money.

Rated 3 out of 5 by from Not as BIG inside as the dimensions state I had intended putting 2 fans beside the power supply as the case advertised. But once the Corsair Modular 750W PS was in the case the 2 x 120 fans wouldn't fit beside each other. I also had to remove the case fan that is mounted at the back of the case as my CPU mounted fan couldn't fit in the case with that in situe. I purchased this case to fit a 1070 as my old case was too small. But this case really wasn't very big as the dimensions stated. I had my old Antec for over 10 yrs. But now I'll replace this Corsair case after a few months i'd say. I bought 2 x 120 and 2 x 140 fans extra. I had to leave 1x120 out and also removed the stock 120 fan. So I wasted money there. The 2x slots for the SSD are in a stupid position. I couldn't close the back panel as the cables prevented it. So In my old case I had them situated with the old SATA Drives is a dual mount. I had to set that back up. This case is value for money. But I really expected more from Corsair. I've been buying Corsair for years now. I won't be buying their cases again.

Rated 5 out of 5 by from Great Case - Incredibly Good Airflow I bought this case with 2x120mm SP120 Corsair fans for the bottom, 2x140mm ML140 Corsair fans for the front and an NZXT Sentry 3 fan controller. I already own a Corsair 240mm AIO watercooler so I have a total of 7 fans, including the rear exhaust. This case fits them all. If you plan on using this many fans, I recommend getting a fan controller as without one it can get pretty loud. Thankfully, I did and I get cool, quiet gaming all day long. The only problem I had with this case was the space behind the backplate. I'm no pro when it comes to cable management so it took me (and a friend) a lot of effort to get the back panel back secured. Overall, The Corsair 450D Airflow is a great mid-tower case for anyone wanting high airflow in a smaller package than the full tower 750D.

Rated 5 out of 5 by from Great mid level case perfect mid level case, with the ability to change the dust filters, add more fans and take out the hard disk holder to provide more air flow. Everything came in one piece and looks good. I'm more then happy with my tower.

Rated 4 out of 5 by from Nice case, plenty of room. Good case, has plenty of room to fit a big radiator. The only fault is the front panel, it is the only plastic piece on the case, and the clips to hold it in aren't good quality, as I found out on the day it was delivered. Scan redeemed themselves and sent me a new front cover, within a couple of days. Great customer service compared to some other companies we work with. Cheers!

Rated 2 out of 5 by from Beware! I spent a long time trawling reviews before i decided on this case, and to be honest now i have it im disappointed. The see through side panel is nothing more than flimsy, mine came with a crack from top to bottom, thankfully Chillblast have agreed to replace it. The brushed aluminium finish to the front panels look scruffy and soon marks with just a slight swipe of your fingers. The front panel covers the two fans and unclips with a gentle push to the top corners, both of these clips were snapped off when my computer arrived and are thin and delicate and totally unfit for purpose, again Chillblast have agreed to replace them. The rest of the case is fine, but for over £100 i expected better, i would not recommend this case.

Rated 5 out of 5 by from Excellent Any new build I make for friends and family will use this case :D , unless they require several rad's. The only deviance from corsair cases I would go with might be the Thermaltake level 10.

Rated 5 out of 5 by from Spacious and sensibly designed I got this case when I bought an R9 280X and discovered that it's roughly the size of the moon and didn't fit in my old case. The case fits in the 280X with room to spare, and has very good air flow with very easy to remove dust filters across all the vents. I also like that the PSU is at the bottom of the case, as it makes it a lot easier to keep the extraneous cables tidy and out of the way (instead of draped over the top of everything). The three fans that come with the case (2 in the front, one at the back) are nice and quiet and shouldn't cause any problems for anyone worried about the sound. All in all, an excellent case, and I'd definitely recommend it to anyone building a new machine.

Corsair H110

Will this fit the cooling kit H110 with quad fans and radiator in the top space, leaving enough room between the ram etc? Motherboard will be the ASUS MAXIMUS VII RANGER
Asked by: JamesD
I bought this hoping for internal space and air flow. I didn't use Water cooling but it's extremely cramped inside once everything goes in. I will be buying a bigger and better case soon. Waste of my money.
