The monolith like Obsidian 900D is classified as a Super Tower rather than the usual mid-tower or full-tower cabinets that we find in general. Mainly meant for water-cooling and building extreme gaming setups or server line ups this is the highest offering from the home of Corsair.
Yeah that's right it can house 15 storage drives! Before we get too much further into this review, I want to be absolutely clear about how the Obsidian 900D is being evaluated, because it's a very different beast from most cases. It superficially looks and is built like an overgrown ATX case, but at an MRP of Rs. 27000 it's about as premium as it gets. We'll start with the review in the following algorithmic manner:
- The Packing
- Inside and Out the Obsidian 900D
- Key Features
- Testing: Load tests and Noise Levels
- To Buy or not to buy?
The PackingWhen you buy a premium cabinet you ought to be worried about its packaging quality and the contents that it comes bundled with from the manufacturer. Especially when you are in India where the transit process is not very gentle to put it right.
Inside the box you receive an installation manual and lots of screws for installing the HDD or mounting fans etc a L-shaped Screw driver is even included to help you install parts in the tight corners easily.
Three 120mm fans in the front as intake and one 140mm fan in the back as exhaust are pre-installed. Don't worry about a ATX12V extender as it is pre-installed inside the cabinet along with the other cables.
Mine came to me traveling half of India and it is in ship shape condition with all the bells and whistles intact. All in all this is the best quality packaging I've come across so far with detailed attention given to every tits and bits.
Inside and Out the Obsidian 900D
- Water-Cooling: The case can accommodate even the largest water radiators available today including those that you can plan on with a custom loop. With a permutation and combination you can increase or decrease the size of radiator you want to install on any particular spot. Giving you the ultimate sense of flexibility.
- Mother-Board Compatibility: It supports all the motherboard form factors ever made and maybe those even that'll be made in future. You can mount a mini-ITX to a HPTX motherboard inside and be still left for enough room to ponder about.
- Dual PSU support: This is a rarity in any commercial grade cabinet. You can mount two individual PSU inside the bottom chamber of the 900D in a vertical position. You want a huge wattage unit for the whole or want to divide the load between two units, it all depends on you and your configuration's requirements.
- CPU Back Plate Cutout: A cabinet of this size is obviously hard to move and open time and again. But this one comes with an open motherboard slot in the back, so that you can change the fittings for a new CPU cooler without needing to take out the whole motherboard outside! That's quality research right there.
- Ample of Dust Filters: It comes with four magnetic dust filters installed which eliminates the problem of a tedious cleaning session of such a beastly cabinet. Their efficiency ensures that your components stay clean and dust free even during a sand storm.
Testing: Load tests and Noise Levels
So on a day with 23 degree outside temperatures, I chose the AMD FX 8350 4Ghz octa-core processor and a XFX 7950 3GB DDR5 graphics card.
In addition the Obsidian 900D was fitted with two Corsair AF 120mm fans added to the top in exhaust mode while the FX 8350 was mounted with a Deepcool Gammaxx 300 Cooler as the stock cooler is very loud and the noise test would have been flawed badly.
