Corsair Obsidian 800D

9.7 Overall Score


The Obsidian 800D arrived at our shop in a straight forward, informative and large box. It is not often that we talk about elegance and home built computers at the same time. But there is something to be said about how simple the box is, yet you get a feeling of power with what resides within. Even the images on the box seem to pull you in.

A box just is a box in the end. It is what lies inside that will keep us glued to our workstation or leave us feeling dissapointed.

The Obsidian was well protected upon its arrival. Plastic seems to be everywhere. Removing all that protective covering can be annoying, however, the benefits certainly outweigh the hassle. We much rather a case be protected, than not. Corsair went to great lengths to make sure that even the precious viewing window was not scratched during transportation. A thin layer of plastic covered the inside and outside of the acrylic panel. You may also have noticed the protective coverings on the more fragile front panel pieces. Not to point any fingers, but Cooler Master could learn from Corsair on how to properly protect a case during transit.

Not being able to wait any more, we pulled off the side panels and started going over this case with a fine toothed comb. Looking inside where the motherboard will sit gives you a bit of perspective as to how much room there is. A great deal of time and energy went into designing the Obsidian to be as easy as possible when it comes to cable routing and installing components.

Many home builders(personal computers, not actual homes) take pride in the work they do to create a masterpiece. The 800D’s cable routing system is second to none and makes life that much easier on the end user. Looking inside this case, you get a feeling of what Da Vinci felt like looking at a blank canvas. A beautiful piece of art sits in the emptyness. It is up to the individual to bring it out.

The Obsidian is a tool less design with feature rich options made to make building a system that much easier. One major example is the CPU socket access panel located on the back of the motherboard tray. We have seen this type of innnovation in many other cases, but Corsair seems to have taken it to the next level. The door reveals a very large hole that will allow access to all different types of motherboards, with the exception of dual socket ones. We welcome this addition of an extra large hole as we found other designs to leave us short with certain motherboards and certain cases. The access panel door allows for added protection from elements such as wires on the backside.

Moving deeper into the interior, we see that there is room for 7 physical expansion slots, with a space for an 8th(maybe a dual slot video card?) as a hangover. The back of the interior has one 140mm Corsair branded fan, two intake/exit holes for a liquid cooling setup and lots of ventilation above and below the expansion slots. Looking at the HDD area, we see a cover that reveals another cooling fan(140mm) used primarily for the hotswap HDD area. Adjacent to that is another cover(not shown) that hides the backplane for the hotswap bays. There is room for 4 HDD’s or SSD’s in this area. As we move up to the top of the interior, we can see there is space for 3 additional 120mm fans as well as plenty of room for a triple radiator.

Focusing our attention on the bottom interior, we see that there is another cover that separates a smaller HDD area with support for two more HDD’s. This bottom area is closed off from the motherboard area with the exception of another 140mm fan and two more holes that allow passthrough for a watercooling setup. A large filter is located down below which is removable for easy cleaning and helps keep the insides of the 800D clear of dust.

As we take our journey to the outside of the Obsidian, we start with the top of the case. Here we get a clearer picture of the top exhaust fans and/or radiator mounting area. The back view reveals a nice little feature that should be included in all cases made. If you look to the left of where the motherboard would sit, you will notice that there is an extra gap between the motherboard tray and the outside case panel. This little gap makes storing unused wires or wire routing that much easier. We are sure that many of you have run into situations where the backside panel bulges a bit because of this tiny area in other cases and the mass of wires you try to cram inbetween the case panel and motherboard tray.

Continuing our tour of the outside of the Obsidian, we have removed the front bezel which allows us to remove the 3.5″ bay spacers and lets us take a peak behind the front panel. There is nothing more here than one would expect. A two bay ‘door’, so to speak, is covering front access to the lower HDD bay. With the front bezel back on, we look at the front hotswap bay door and the trays inside. The door works as it should. We would also like to note that the hotswap trays support 3.5 and 2.5″ drives. There is no adapter needed to mount an SSD or notebook HDD.

We finish the unboxing with a quick look at the bottom of the Obsidian 800D. You can see where the filter sits and the placement and construction of the support feet. Up next is our installation segment and system setup information.
