Introduction, Specifications, and Pricing
Corsair is no stranger to our test bench, whether it be RAM, coolers, or the plethora of other devices they make these days. While Corsair started life as a memory company, the past several years, they have upped their game in the chassis department. Corsair has not only had some of the current trends integrated into their chassis rather quickly, but Corsair has also helped foster adoption for various chassis trends and even led the market in several instances.
Today we are looking at one of their recent chassis releases with the Carbide 678C. The Carbide series has hosted some impressive new chassis throughout history from the cubic AIR 240 and 540 to even the 740. They also have included more mainstream models such as the current SPEC series and 400Q and C. The Carbide series has always been a mix of steel with some plastic trimmings for aesthetic.
With all of the previously mentioned inclusions, the 678C is looking to make a mark on the market with a reliable mid-tower option with sound deadening and tempered glass much to the likes of something you may see from Be Quiet or Fractal Design. The 678C is designed for enthusiasts looking for versatile cooling fitment, modularity, and an overall robust build platform. The 678C much to my surprise is sans RGB, which is counter to typical Corsair style as they have focused on their new iCue management suite and their ability to RGB all the things.
The key features according to Corsairs page for this chassis are as follows:
- Optimized for quiet operation
- Modular design to allow versatile cooling placement
- Extensive sound deadening
- Multitude of cooling options
- Integrated PWM fan Repeater (PWM Signal Hub) Supporting six fans
- USB 3.2 gen 2 Type-C port
- Versatile storage options via modular trays
- Easy accessibility via Hinged door style front and main side panel
The chassis, as mentioned previously, is the Carbide 678C, part of the Carbide series with the part number of CC-9011170-WW. This is the White version of the chassis, as the Black version would be part number CC-9011167-WW with all other parts remaining the same. The chassis measures in at 549mm tall and 497mm deep, and a width of 239mm. This fits well within the commonly accepted Mid-Tower designation. The width of the chassis will help a bit with the ability to install components, and I hope this means clearance for a proper RAM set this time while having a top-mounted AIO.
Motherboard fitment for the 678C is from ITX up to EATX. The extra width is nice since the motherboard tray is a bit recessed, as you will see in the pictures on the following pages. This means that most high-end enthusiasts boards will fit without issue. HDD fitment is up to six for 3.5" drives, but if you can get extra trays, there are two additional spots left open, which could raise this limit to eight. There is a small plastic SSD caddy running across the rear of the motherboard tray that allows tool-less SSD installation or removal from the caddy.
One addition I have not seen in quite a while is a 5.25" opening in the front of the chassis once you open the front door. The 5.25" mounting is removable to expose more top-mounted cooling fitment, but it is there in case you need it. The PSU is limited to 225mm if you want to consider that a limit, so we know you can fit most any PSU in the space at the lower chassis. Speaking of the PSU area, there is a PSU shroud in place to make for a cleaner overall build. The PSU shroud has an elongated cutout upfront to support thick radiator mounting at the front of the chassis.
Cooling fitment is quite versatile as Corsair states with up to eight 140mm based fans and nine 120mm depending on your preference. The top can support triple 140mm or triple 120mm, while the front can support dual 140mm or triple 120mm. The rear can support either a 120mm fan or 140mm. The bottom can support up to dual 120mm or dual 140mm fans, respectively. Radiator fitment is quite similar; just keep in mind that 360 or 420mm based top-mounted radiators will require removal of the 5.25" mounting. Preinstalled fans are totaling three, all of them 140mm based and mounted with single units in the front, the top, and the rear. CPU air cooling height is limited to 170mm, which is plenty for most high-end air cooling solutions.
The price for the 678C at the time we started writing was $179.99, but as of completing testing, it is now $149.99, which is a great new value proposition coming down like this as the 678C now has an entirely different batch of competitors to contend with. Had we left the price at $179.99, the 678C would have been head to head against cases such as the Vector RS from Fractal and the Define S2 vision, which is both powerful and troubling competitors. Now, we find that the 678C with its new price being placed against The H510 Elite from NZXT, the Define R6 and Meshify S2 form Fractal and the Silent base 801.
