Which Way Does the Motherboard Go?


Horizontal Orientation


Vertical Orientation

However you like it The motherboard for the Core V21 can either be mounted in a vertical or horizontal orientation designed to offer customisations that reflect the enthusiasts personality whilst providing the best viewing presentation and still ensuring unbelievable cooling performance. A removable dust filter has been embedded to the bottom panel of the chassis and shockproof rubber gaskets on the PSU bracket aim to reduce noise during operation.

Unprecedented Flexibility for your Thermal Solution


It's Your Chassis Make it UniqueWith 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.

No Limit to your Build Creativity


Remarkable ExpansionDesigned 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 GPU 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 liquid cooling performance

Does it's Size Affect Airflow?

Well Ventilated

optimised VentilationWith 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.

What About Storage Options?

Chamber Design

Compartmentalised Build DesignThe Core V21 is optimised for space management. The chassis is divided into two main chambers: the upper chamber is made for cooling performance and efficiency, while the lower chamber 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 system builds.

Exclusive Thermaltake Certification

LCS Certified

Liquid Cooling SupportedTt 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, Black, Micro-ATX Mesh Stackable Cube PC Chassis /w Window, 1x 200mm Fan, 2x USB 3.0, mATX/mITX is rated 4.7 out of 5 by 23.
Rated 5 out of 5 by from Perfect! And So Many Options I needed a well budgeted cube case purely to fit into a tight spot and still perform. The options for fitting your components to this case are almost endless! I only ever expect to fit the board a couple of drives and maybe a slim PCI device in a cube case. There’s room for more than 2 PCI, Lots and Lots of drives, Lots and Lots of fans and the whole case can is quite modular. I’ve installed lots in there and there’s still a lot of room for air to circulate. Well designed and was perfect for my functional and aesthetic needs. Design is sleek and the huge main fan is more or less silent.

Rated 5 out of 5 by from Perfect Where to start on this. The case looks amazing, everything fits perfectly inside and I love that there are Motherboard standoffs pre made in the case. The cooling is just amazing and the cooling potential is mind blowing. I recommend this case for those who are looking for a mATX case that is not a standard tower.

Rated 4 out of 5 by from Bigger than I expected Nicely constructed, easy to build in. Larger than expected (though the measurements are given! Possibly bigger than it needs to be.)
Date published: 2020-05-05
Rated 5 out of 5 by from Great Case. Very good price and quality. Wanted something different to a tower case and this one was the right choice for me.
Date published: 2020-04-27
Rated 5 out of 5 by from Excellent product This is a great case. However, one must be aware that for a Micro ATX motherboard is quite large but does give plenty of space and room to add larger components. For example, the Be Quiet Slim Rock air cooler first perfectly within this case. I would recommend this product.

Rated 5 out of 5 by from Spot on! This a great case if your building a matx setup and have room for it, It is really good for modding. well what can I say about SCAN, As too my dealing with them they a top notch firm with great service and quick delivery thank you.

Rated 5 out of 5 by from Outstanding value & very easy to work with This case is deceptively amazing for what it allows you to do with a microATX build. It's also big enough to accommodate a 33cm long video card; I use with a Zotac Amp Extreme GTX1070, which is a physically huge card - 32cm long by 14.5CM high and 2.5 slots wide. There are multiple HD and 3 x SSD mounting bays included. As supplied, the case has a large, nearly-silent 200mm fan at the front which blows over the whole interior. You'll need to supply a PSU and a rear exhaust fan if you're going with conventional air-cooling, but there is amazing flexibility on offer here. The motherboard mounts horizontally rather than vertically, which also helps with cooling the entire motherboard and allows the GPU to vent heat vertically straight up rather than over the video card PCB. With a 120mm exhaust, the exhaust breeze blowing out the back always feels cool. All the side panels are removable (and in fact, this case is intended to be stacked on top of another V21; if you wanted, you could fill the second case entirely with watercooling reservoirs & radiators etc.). The side panels are all removable via simple thumbscrews, and feature 1 panel with a window and 2 with magnetic mesh air filters & air vents running the full size of the panel underneath. Inside, the case also has 4 brackets supplied which, if you don't use them will be invisible behind the air filters, but allow a lot of extra possibilities. The brackets are intended to fit over any the top or side-panels, and allow you to mount a huge variety of cooling options - two 200mm fans, up to eight 120mm fans, "all-in-one" watercoolers or custom watercooling setups - there's a deceptive amount of room inside. My only complaint is that the PSU sits in its own dedicated bay immediately underneath the CPU area of the motherboard, and under full load, the PSU can generate a good volume of warm air which will inevitably warm up the motherboard somewhat. Nonethless, this is counteracted by exceptional airflow over the components from the large front fan. For the price, however, this case is a striking visual change from the standard towers everyone uses, and has amazingly well-thought-out possibilities - you can build a machine to rival the fastest tower you can think of with one, or even two of these.

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!

Asked by: Titch
As long as it is a micro -ATX board it should fit, just had a quick search and it looks as if your board is a full ATX if so sorry but it won't fit in this case

200mm Fan : is it 4-pin PWM or 3-pin?

The 200mm front intake fan that comes with this case/chasis, is it a 4-pin PWM fan or a 3-pin fan?
