System76 unleash a quad-GPU Linux monster with the 'Thelio Mega'

By - | Views: 24,266

What has four GPUs and could probably heat up your entire house? System76 have announced the Thelio Mega and it's absolutely ridiculous.

System76 say that the Thelio Mega is the world's smallest quad-GPU workstation primarily made for deep learning and scientific computing. I'm sure that won't stop someone trying to play games with it though as this might be (probably is) the most powerful Linux desktop you can buy and it's gorgeous too.

"Thelio Mega is our LeMans hypercar," says System76 CEO Carl Richell. "We've put all of the most advanced engineering and technology into Mega with stunning results that perform well beyond industry standard quad GPU systems. It's compact, quiet, exceptionally performant and strikingly beautiful."

Ready to uncontrollably drool? Have a look at some of the possible specifications:

Operating System Pop!_OS 20.04 LTS (64-bit) or Ubuntu 20.04 LTS (64-bit)
Processor AMD 3rd Gen Ryzen Threadripper

Up to 4x NVIDIA including:

GeForce RTX 2080Ti: 3 × DisplayPort, 1× HDMI, 1× USB Type-C
Quadro RTX 4000: 3 × DisplayPort, 1 × DisplayPort over USB-C (VirtualLink)
GeForce RTX 3090: 2 × DisplayPort, 2 × HDMI
Quadro RTX 5000: 4 × DisplayPort, DisplayPort over USB-C (VirtualLink)
Quadro RTX 6000: 4 x DisplayPort, DisplayPort over USB-C (VirtualLink)
Quadro RTX 8000: 4 x DisplayPort, DisplayPort over USB-C (VirtualLink)

RAM Up to 256 GB Quad Channel DDR4 @ 3200 MHz
Storage Up to 62 TB, 4 × M.2 PCIe Gen4 NVMe and 2.5′′ SATA drives
Rear Ports 7 x USB 3.2 Gen 2 Type-A, 1 x USB 3.2 Gen 2 Type-C, 2 x RJ-45 LAN
Rear Audio 5 x Audio Jacks
Networking Intel® 10GbE LAN chip (10 Gbit/5 Gbit/2.5 Gbit/1 Gbit/100 Mbit), supporting 2 RJ-45 ports
Built-in Intel® Wireless-AC (a/b/g/n/ac/ax) with Bluetooth 5.0
PSU 1600W 80+ Certified (90% or greater power efficiency)
Case size Height × Width × Depth
18.82′′ × 10.35′′ × 17.24′′ (478 × 263 × 438mm)

With all that power comes great responsib…heat. That's why System76 took great care with the airflow on the Thelio Mega. Rather than a single vent for the system, they have intake fans on the bottom and side panels to feed cooler air directly onto the GPUs. They said that everything "down to the GPU brace, developed to secure GPUs for transit, has been tested for maximum thermal efficiency".

That's not all though, there's a separate duct that isolates the airflow to the beastly AMD Ryzen Threadripper, plus a dedicated intake vent on the side to send a cool breeze towards the heatsink too. They're using a "closed-loop phase change" which has actuating fluid evaporate into a gas to draw thermal energy away from the CPU and towards the heat sink, where it's then cooled into a liquid and returned to the transfer plate. After that, all the hot air then exits via the exhaust port. They say doing all this gives performance "similar to if the components were sitting on a test bench". So they have some fancy water cooling system in place.

To top it off they have large 120mm and 140mm fans for each section plugged into their dedicated fan IO board, and then tied into a Thelio IO board. System76 said this design "allows for each thermal system to be independently controlled for maximum performance, as well as for easy servicing - when panels need to be removed, simply unplug the fan IO board and slide off".

I absolute adore the vent design on this, such awesome style. Honestly, if System76 sold their own cases for generic systems for users to make their own, I would quite probably buy one because they look so sleek.

Just like their previous Thelio units, the Mega is "open source hardware" which they have up on GitHub and it's hand-crafted in their own manufacturing shop in Denver, CO.

Available from today, pricing starts at $7499.99. See more on and head direct to the Thelio Mega page here.

About the monitor: the Dell U3011/14/17 (30 inch, 16:10 aspect ratio, 2560x1600) is still my dream peripheral. May the Lord permit I'll afford one, one day
