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 4.4 out of 5 by 7 reviewers.
Rated 5 out of 5 by great value matx case! this is a really good bang for buck micro atx case. looks really stylish and sits on top of my desk nicely. has amazing airflow thanks to the huge open side panels which have dust filters. i have window on top and mobo sitting horizontally and the 200mm front fan blows straight across components including two hdd down in the bottom trays. because of the fact you can hide all cables from psu down underneath i have non modular psu but all cables not in use are bundled together with ties it leaves unrestricted airflow around all your main components, is an amazingly tidy case thanks to the awesome cable manegement options. also was a pleasure to build with because all panels come off you can easily fit everything with ease. only downside is have to remove mobo to fit backplates for cpu coolers as mobo sits directly on top of psu. i set this up with an i5 4690k corsair h100i gtx 970 and im so happy with it! i honestly would have expected a case like this to be more expensive. highly recommended. 19 April 2016
Rated 5 out of 5 by Looks great and is so customisable Great case. I am so pleased. Plenty of room for anything you can think of. Very customisable in so many ways. Would highly recommend this one. 26 January 2016
Rated 5 out of 5 by Core V21 case for mid range gaming PC I took long time before deciding on which case to buy as i was looking for best compromise between good value and aesthetics. I wanted to use something smaller and visually pleasing which i could also keep on the desk. After some time considering the looks, size and price i ended up choosing Core V21 from ThermalTake. Receiving the case, i imagined it to be a bit smaller. From the box, it comes with 2 mesh panels, 1 glass panel and bottom panel. Side mesh panels have magnetic dust filters. It also comes with huge 200 mm front fan. Front panel rotates and you can position front I/O inputs (usb 3 ports) on the side you want although cables may not reach motherboard in certain position. It can be only positioned on left side of the panel. There is possibility to add extra fans or water cooling radiators using included 4 rails (possibility to add fans or radiators on different sides. As it can fit atleast 4x120mm fans or 2x140mm fans, it should fit same size radiators. More details needs to be checked from their site as i had no need for extra rails nor did i use water cooling). I ended up just adding 140 mm fan as exhaust in rear. That and the front 200 mm fan is more enough on low speeds to provide quite good airflow, more than average user needs. Noise is quite low and is not heard over my gpu fan (must be somewhat bent or something as fan noise disappears once applied pressure to the frame. All said the included fan has tolerable noise, especially using it outside bedroom. As you can see from the picture attached, there is a lot of space inside the case. Since the case has a 2 floor system, you can even get away by just using non modular power supply, which helps when you are on tighter budget. Also all this space helps to keep the case cooler and it made installation really easy for me. As you can remove all panels besides rear helps a lot. As said this system keeps first floor nice and clean to allow good airflow and together with glass panel (i'm using it on top) it gives nice and sleek look. The big frontal fan also helps cooling ground floor where there is rack for 3 conventional HDDs, PSU bay and i believe there was 3 SSD quick mount slots. Default flat surface layout relieves pressure to motherboard caused by huge and heavy graphics cards and cpu coolers. Huge plus side for this case is that it can fit really long graphic cards and big tall cpu air coolers. This was one big factor why i decided for this case as i wanted to run my system cool. I fitted into this case an ASUS GTX960 turbo (reference cooler) and i5 6500 skylake with Hyper EVO 212 cooler with non modular PSU. This setup runs ridiculously cool on room temperature (around 20 degrees celcius), idle temperatures for cpu are around 24 degrees celcius (skylake seems to be one cool chip) and around 24-26 celcius for gpu. Under load, processor reaches 40-50 celcius and gpu 50-60ish celcius. That is while playing modern titles on maximum settings. Might go a bit higher under stress tests but that doesn't really matter everyday. As far as my experiences go, would i recommend this case? I would certain do. PROs * Lots of space (room for big cards and coolers) * Dual floor build for nicer and cleaner look (fits normal size PSUs) * Space to hide extra cables, custom controllers etc * Plenty of room to install and cable manage * Movable panels * Lots of room for extra fans, radiators etc * Looks nice and solid CONs * Could be cheaper * Too long, could make it more cube shaped. * For the price only 1 fan added * No 5.25 bay for DVD writers etc * Wish there was option to choose different color scheme 05 January 2016
Rated 4 out of 5 by Very interesting design and well built Good case loads of room for everything and then some. easy for good cable managemnt and lots of space for rads, expansion and umpteen HDD, including thoes nice little SSD trays 19 December 2015
Rated 4 out of 5 by A few kinks but otherwise a good case. I bought this based on the horizontal motherboard tray as my old water cooled GTX 680 was sagging to a point where I felt it was going to snap off the motherboard in my old case. As a single case it is really nice - it's functional and it's compact, with enough space inside for a good build. It's also a really cool feature that the case isn't a set-in-stone layout as you can use it in different setups simply by changing the external panels to different sides (the sides can become the top/bottom, and vice versa). One thing to note though is that if you try to cram too much in to this (as I did) with things such as water cooling loops, then you may encounter some pretty warm exhaust temperatures as it will build up pretty quick inside. For this reason I bought a second case and "stacked" them. This is where I am a little annoyed TT. The case is designed to be stacked with other V21 Cube's, yet there are no PSU or I/O panel covers supplied. You can't even buy them on the TT store? So now there are 2 gaping holes in the back of my case until I decide to have a company fabricate them for me... specialist stuff usually. This is a pretty fatal design flaw aesthetically and functionally as the airflow gets thrown off and it's ugly as sin having the holes in the back. Overall I do recommend this case if you are looking for a horizontal layout or even just a well priced and sturdy little box to run a system in. The build quality is surprisingly very very good - it's more sturdy than most of the expensive cases I've bought in the past from NZXT, Corsair, Coolermaster and BitFenix. But just be aware that you will probably have to shell out for the extras if you stack them and, like me, can't just leave those holes in the back. 17 August 2015
Rated 4 out of 5 by Good little case, almost no flaws I bought this case as my previous one was too big so I wanted a new one. The looks of the case is very appealing and despite being small, the space is used very efficiently so you can fit large components as well as an SLI/crossfire rig. My main issues are that there is no 5.25 bay, there IS a 5.25 slot but that's it, you could make some sort of bracket for a disk drive but you'd need to take the front panel off to use it. My other only issue is airflow, unless you have good/lots of fans it can get hot. I have an h80i and still idle at around 40 degrees rather than the 30 with my more spacious case. The fact that every panel fits each side is very nice so you can have horizontal or vertical mobo placement and still have the windows showing inside. I have mine horizontal because it looks much nicer that way. 08 August 2015
Rated 4 out of 5 by Good for the money This case is similar to the corsair air 240 but much cheaper. It is made of thick metal with an excellent psu positioning similar to that of itx cases. It's dust filters on the side panels stop large dust particles but allow fine dust to enter. There are 2 identical side panels with dust filters and one window panel. You can purchase extra windowed panels separatly. My case didn't have the blue led 200 mm fan but instead it came with a black 200 mm fan. Did I get the wrong product? However the case is very good value with some defects such as the common too long USB 3.0 cable. This clutters the case close to the windowed panel which is a shame. The case also as black front panel connectors. Very impressed. There are 5 pci spaces allowing sli or crossfire for up to 2, 2 slot cards. Not recommended in my opinion due to thermals in a small case. It has space for 7 x 120 mm fans without the 200 mm stock fan. The case is also stackable allowing unlimited water cooling potential and I would like to see the amazing creations of our world most creative pc moders and buidlers. Well done on keeping the cost down thermaltake. 21 January 2015
