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.

Thermaltake Core V21 micro-ATX Mesh Stackable Cube Computer Chassis with Window Panel, USB 3.0, 200mm Non-LED Fan is rated 4.7 out of 5 by 12.
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.

Rated 5 out of 5 by from Fantastic little case! Can't recommend this case enough if you want a nice somewhat compact case (is quite sizeable considering the form factor). All surrounding panels are removeable via thumb screws, so access is as good as it gets. 2 panels have magentic washable filters whilke the other is the window panel. Plenty of space for even the longest graphics cards and can even fit 2 240mm water cooling systems. Can't recoomend this case highly enough! Would definitely buy again for another mAtx build.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from 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
