The Beast


What do I get when buying The Beast?

The Beast is composed as follow:

- 2 heatsinks

- a case in 6mm black painted aluminum & textured aluminum

- black shade tempered glasses (standard) or aluminum panels (options)

- a front panel (power button, audio & micro, 1x USB C, 2x USB 2.0, 2x USB 3.1 Gen.2)

- a GPU spreader or a machined heatsink for VRMs + taped heatsinks for memories

- a custom riser PCI 16x Gen4

- a kit of Gelid Ultimate thermal pads

- a kit of extended cables for back panel (1x HDMI, 2x Display Port, 4x USB 3.1 Gen.2, 1x USB type C, 1x RJ45)

What is the weight of The Beast?

The Beast is quite heavy.

What are the dimensions of The Beast?

The Beast is 450mm x 380mm x 210mm.

Does it really make no noise?

For configurations up to 150W CPU and 250W GPU, The Beast is cooled passively without any fan. For higher configurations, The Beast is cooled silently with low speed 140 mm fans installed on the top of the chassis. In this case, the fans are only activated during short period of time in the event of intense computing (benchmark, software calculation, AAA Games, etc.). From an electronics perspective, some electronics components may intrinsically produce “coil whine”. This electrical noise is independent of the cooling solution and can be avoided by selecting premium brands.

Can I choose the color of my Beast?

The Beast is available in black as standard (30% shiny) and can be customized in any color by selecting the option "color". The colors available can be seen there.

Is there any thermal impact by choosing the glass panels instead of the aluminum panels?

No, the sides parts are not active, only the front and back panels are connected to the thermal drains and spread the heat.

How can I assemble The Beast alone?

Have a look at our User Manual following this link.

Feel free to join our Discord to directly discuss with the team and the community.

How can you provide right brackets / spreader for my components?

When an order is placed, each client receives an automatic email confirming the order and asking which motherboard and graphic card he plans to mount into his Beast. By answering this email, the team will be able to add the right brackets and/or spreader into the package. Each bracket is also available for free online for next upgrades of components.

I don’t want to assemble The Beast alone, what can I do?

Configurations are available following this link.
Do you have special needs? Feel free to contact the team to discuss about the configuration you would like at

MonsterLabo can also assemble your components. Choose the option "Assembly" when your place your order. We will take care of the assembly and fanless optimization for you.

Is there a risk to pay preorders that will be only shipped the next quarter?

If you feel like uncomfortable paying for preorders, feel free to use Paypal that offers 6-months guarantee in case of refund. We also invite you checking your bank conditions that might apply some guarantee in case of refund.

How can I know the unit number of my Beast?

The Beast is numbered. The unit numbers are engraved at the very last, before finalizing your order and shipping it to your address. This to avoid any changes due to potential refund requests. If you want an estimation of your unit number, feel free to contact the team at


Is The Beast compatible with my motherboard?

The Beast is compatible mini-ITX > ATX. We didn’t notice any issue with specific motherboards so far. The compatibility list is updated regularly.

Is The Beast compatible with my graphics card?

The Beast is compatible with most of the graphics cards up to 290 mm PCB length. Have a look at our compatible list. This section is updated regularly.

My graphics card is longer than 290mm, why is it compatible?

A graphics card is composed of a PCB with a housing (heatsink and fan) mounted onto it. The assembled graphics card can be longer than the PCB itself. The effective length to take in consideration for The Beast is the PCB length. This explain why some graphics cards are compatible although being longer than 290 mm, housing included.

Is there any warranty problem to remove my graphic card heatsink and fan (HSF)?

To mount the graphic card onto The Beast heatsink, you will have to remove the HSF (heatsink and fan). This step is mandatory to have a passive computer. Each graphic card manufacturer has its own warranty policy regarding the disassembly of the HSF. Please refer to your card specification. Disassembling a card is a quite mainstream process in all high-end cooling solutions, liquid cooling being the most common example.

What about cards not compatible with a full covering spreader?

The full covering spreaders was designed for cards with a TDP higher than 220W. For the other cards, a machined heatsink for the VRMs and heatsinks for memories are enough to keep the board cooled. We also designed a special solution for some boards (RTX 3070 mainly) made of a spreader for memories, combined with a machined heatsink for VRMs.

How my motherboard will be secured into The Beast?

ATX motherboard do not get their weight allocated equally. That means a loud part of the board can not be connected to the cooler block. To avoid any issue, special brackets are designed to fix the motherboard to the structure. Formats smaller than ATX are not concerned by this potential issue.

What about cards not listed on your website?

Many references have been added into our “compatibility” section but not all of them at listed. For graphics cards, most of the time this is due to the lack of pictures available online. Feel free to contact us if you need us to check a specific reference.

Is The Beast compatible with my power supply?

The First is compatible with SFX, SFX-L and ATX full length power supplies.

How many storage drives can I install into The Beast?

The Beast allows the mounting of 4 HDDs 3.5’’ or 8 SSDs 2.5’’. Please note we do not recommend the installation of HDDs that can be very loud, especially into a fanless case (=0dB).

Is The Beast compatible with 200mm fans?

The Beast is not compatible with 200mm fans for now. A solution is currently studying to allow the mounting of 200mm fans at the bottom of the case.

Is The Beast compatible with PCI card?

The Beast is compatible with PCI card. With mini-ITX motherboard, it can be connected directly onto the board. With other formats, you can use one of the two back panel slots with a dedicated 3D printing part, or you can use the HDDs slots that are compatible but will require the using of a riser.

Do you offer warranty or support?

We offer a 2-years guarantee in the European Union, 1-year elsewhere for the mechanical and cooling parts.

What is the maximum TDP?

Power max CPU: 300W

Power max GPU: 320W

What is the recommended configuration?

In full fanless mode:

  • CPU: 150W

  • GPU: 250W

In silent mode (2x 140mm at 500RPM):

  • CPU: 250W

  • GPU: 320W

What are the solutions to optimize cable management?

Cables management is a critical aspect for 2 main reasons: (1) it has an impact on the interior aestheticism of the case and most important, (2) it can impede air flow and reduce passive cooling efficiency if not properly done. Although cables management of The Beast can be done quite easily with standards length cables, we will propose custom cables options with specialized partners. Additional cables are already included with The Beast. Their length optimizes the cable management and air flow into The Beast. We also designed special parts for cable routing available at the bottom of the case.
