Product Overview As the latest addition to the Core V Series, the new Thermaltake Core V21 is a quadrate micro M-ATX-based chassis that offers an endless stackable and flexible thermal solution. It allows externally-modular upgrades for enthusiasts to create dual systems. Designed for use in either a vertical or horizontal orientation on the motherboard, users can customize the chassis for the best viewing presentation. A 200mm fan on the front panel ensures that the Core V21 delivers outstanding cooling performance with compatibility for extensive DIY/AIO LCS, further enhancing the reputation that the air cooling units of the series has become renowned for. Guaranteed to be an immensely powerful system, the Core V21 also has the ability to accommodate various overclocking components to boost performance even further where it counts! FeaturesVertical or Horizontal Motherboard Placement - The Core V21 is designed for use in either a vertical or horizontal orientation on the motherboard. Built for customization that reflects the enthusiast’s personality, it allows for adjustments to the chassis for the best viewing presentation while ensuring outstanding cooling performance. A removable PSU dust filter is embedded in the bottom panel of the chassis. Additionally, shockproof rubber gaskets on the PSU bracket help to minimize noise during operation.
Stackable and Flexible Thermal Solution - With its endless stackable design, the Core V21 is in a class above the rest. Virtually limitless utility is possible. It’s the first expandable system that allows enthusiasts to incorporate externally -modular upgrades. Stacked together, the chassis opens up space to expand the liquid cooling system, the storage solutions, or even create dual systems, thereby allowing for a dedicated top/bottom set-up for pure cooling. The maximum radiator length supported is 600mm at the front of the stack.
Remarkable Expansion - Designed for high-end gaming system compatibility, the Core V21’s modular drive racks allow gamers to easily install up to six data storage devices, a dual expansion slot VGA up to 350mm in length, and a tower CPU cooler up to 185mm in height. Even with a high-wattage PSU of up to 200mm in length, there’s still plenty of space available for cable management. Moreover, two 240mm radiators can be installed on top of the chassis, delivering superior cooling performance.
Optimized Ventilation - With its exceptional cooling ability, the Core V21 offers various mounting points to support all types of cooling systems, including DIY/AIO liquid-cooling systems and air-cooling units. A large 200mm fan is preinstalled on the front to guarantee that any type of gaming system can be accommodated.
Chambers Concept - The Core V21 is optimized for space management. It is divided into two main chambers: the upper chamber is made for cooling performance and efficiency, while the lower one is made for PSU and drive bays. Thanks to the removable 2.5”/3.5” drive device racks, there is plenty of flexibility to gain the maximum interior space when needed for advanced cooling performance or liquid systems build.
Tt LCS Certified - Tt LCS Certified is a Thermaltake exclusive certification applied to only products that pass the design and hardcore enthusiasts standards that a true LCS chassis should be held to. The Tt LCS certification was created so that we at Thermaltake can designate to all power users which chassis have been tested to be best compatible with extreme liquid cooling configurations to ensure you get the best performance from the best features and fitment.

Rated 5 out of 5 by from Excellent product Was just shopping for a small cheap case to put my sons PC build in - but OMG was I surprised when this arrived. Excellent quality, well built and super good looking. Going to order two more and swap my PC and water cooling into these cubes. Seriously - a really good buy and so versatile!

Rated 4 out of 5 by from Great case with only a couple problems. So overall I would say this case is worth the money, the case looks great and it fits in everything that I need however when building I noticed only 2 problems. Problem 1: There is a power supply supporting bracket that is designed to help hold the power supply up however it does not fit my Corsair AX860I as the fan cover extrudes outwards. This is not a big issue but it's something to note. Problem 2: This case has 3x 2.5" SSD Drive bays and because of the orientation of the drives my SATA power connectors had trouble reaching all of the drives and it was a pretty tight cable run, I had to put a lot of force in connecting all the drives with one SATA power strip so keep that in mind. Apart from those two problems which are pretty easy to fix or work around the case is extremely nice and I think will please most people.

Rated 5 out of 5 by from V21 core, great Micro ATX case Great case, easy to build on, plenty of room for big graphics cards, good value. Would like to buy more clear panels for it but after a quick search I think you can only get them from Thermaltake in the US.

Rated 5 out of 5 by from Excellent Built a micro system for a friend using this case , and was impressed with the design . I found it very easy to build the system and keep all cabling tucked away to keep it tidy and maintain a good air flow . If you are not using water cooling , the 200mm front fan as an intake paired up with a good quality 140mm exhaust fan will be more than enough to keep any sensible gaming rig cool and quiet . I am now going to be building a water cooled version for myself , so I will update once done .

Rated 5 out of 5 by from Excellent mini server case I bought this case to replace a Thermaltake Core V1 that I was using previously for my plex media-server I loved the Core V1 but it only had room for 2 SSD's and 2 HDD's which sadly I had outgrown. The build quality of this case is superb, the magnetic dust filters are an excellent addition over the V1, and the extra HDD space and cable management space is very welcome. It is a bit larger than I thought in the photos but fits under my desk out the way quite nicely.

Rated 5 out of 5 by from Amazing case, easy to mod What a great case, I recently changed my system from eatx to micro atx and was torn between this case and the node 804, so I brought the node 804 at twice the price of this case, I struggled to get everything including my custom water loop into the node, also found out very quickly that you have to build it in a certain order to get everything in, otherwise you find yourself removing bits time and time again to give yourself room to install other parts. So I thought, I'll give this case a try knowing it was slightly bigger, wish I had of gone for this case in the first place, and at only £47 it's a steal. I wanted the vertical mobo mount option in this case, I then cut the rest of the holes out at the front of the case with a dremmel not the best job, but it does, sort of difficult with a tool that only really cuts in straight lines, speedlic metal cutting discs, this was so I could mount a 240mm radiator in the front vertically, its already setup for a horizontal mount with the case in this orientation, but you end up with a lot of wasted space, to my surprise after fitting I realised there was plenty of room for a push pull configuration, and also managed to squeeze my pump in right next to it, so I cut down 2 of the radiator mounting brackets, drilled a couple of holes in the side of the case where the power supply fits, and stuck another 240mm vertical radiator in there, there's even enough room for another 240mm radiator in the top of the case with the 2 rails I have left, and a 140mm at the back, for a micro atx case, the watercooling possibilities are endless, I also removed the 3 ssd drive bays and mounted all 3 of my drives in the hard drive cage below the power supply, taking a closer look at this bay, it looks like you can fit a small fan, possibly 80mm in there to blow over your hard drives, cable management is a breeze as long as you plan it out and are careful with it. The pictures show the build, the white tissue you can see in there is for leak testing of the loop, I couldn't recommend this product enough.

Asked by: Titch
Hello, This case only supports Micro ATX and Mini ITX motherboards. The ASRock 970 Pro3 is an ATX board and would not fit in this case. Regards,
