Atlas
Thank you for your interest in the Atlas. This is
a multi-orientation test-bench style computer
chassis. It accommodates Mini-ITX, Micro-ATX and
Standard-ATX motherboards. The hole patterns on
either side of the motherboard support 240, 280,
and 360mm radiators. The purpose of this design is
to support as many combinations of components as
possible on a platform that is easy to build on, and
aesthetically pleasing.
The Atlas is the evolution of a traditional bench
that was built for in-house testing. This design
is the result of equal consideration of form and
function. It began as a simple “W” shape that was
gradually adjusted to accommodate most common
components. Our aim was to support various hole
patterns using the minimum amount of steel. Ideally,
this is the only test bench serious users would ever
need, and/or a robust open air chassis for someone
to use as a workstation computer.
The Atlas consists of 3 pieces of steel that are
painstakingly cut, bent, and finished to the highest
possible manufacturing standards. The PSU flange
and GPU mounting bracket are attached to the
main part with 6/32 fasteners.
This is a project kit designed for advanced PC
builders who have experience and familiarity with
the challenges of custom PC building. We hope this
product will be an important part of your next build
and that you will make something both useful and
captivating. Enjoy!
-Eric and Ken, Yuel Beast Designs

Weight of Chassis & Flanges: 18 lbs
Ships in a 20” x 20” x 16” box

Each main chassis and GPU flange begin as 4x5’ sheets of 7 gauge hot rolled pickled & oiled steel. The
PSU flange is made from 11 gauge cold rolled steel. The parts are cut on a 3000 watt CNC fiber laser. The
primary part is bent in six places using a precision hydraulic press brake. The GPU mounting bracket is bent
and tapped to ensure accurate alignment for the GPU thumb screw. All stand-off holes are tapped using a
6-32 cutting thread. The paint is a textured black powder-coat.

Assembly Instructions
1. Begin by sliding the 4 rubber u-channel guards on
to the bottom edge of the chassis, two towards the
end of the radiator mounts and the others on the
short edge of the struts. Turn the chassis upright to
sit on the edge guards (figure 1).
2. Line up the PSU flange with the 6 mounting holes so
the short end of the flange is pointing down. Screw
the PSU flange into place. Line the GPU bracket up
with the 5 mounting holes and screw it to the back
of the chassis (figure 2).
3. Apply the 4 rubber feet to the back of the struts
(figure 3). Double check that the orientation of the
PSU flange is correct, then line the PSU up with the
appropriate hole pattern and fasten the PSU into
place. Return the chassis to a horizontal position.
4. Take note of the motherboard you’re using and
determine which set of holes will be used for the
stand-offs. The Atlas can accommodate Mini-ITX,
Micro-ATX and Standard-ATX motherboards. Screw
the stand-offs into the correct pattern and screw the
motherboard onto the stand-offs (figure 4).
5. Seat the GPU into the desired PCIE slot and mount
it to the corresponding hole in the bracket using the
thumb screw.

Component Compatibility
Motherboard
The Atlas can accommodate all Mini-ITX, Micro-ATX and Standard-ATX motherboards. Extended ATX
boards can also be mounted, however it will overhang in the direction of the radiator mount on the right
side.
GPU
There are no limitations on GPU slot width, or the number of video cards you can install. The maximum
GPU length somewhat depends on what you have installed on the inside of the radiator mount on the right
side. Please see clearance measurements below:
Nothing installed inside: 336mm / 13.25”
25mm fan: 311.8mm / 12.27”
29.5mm Radiator : 307.3mm / 12.09”
29.5mm Radiator + 25mm fan: 282.3mm / 11.11”
2.5” Drive Mounting Holes
There are two sets of mounting holes on either side of the motherboard. You may use the pre-installed M3
screws to mount drives to the underside of the chassis.
Power Button Mounting Hole
The Atlas ships with an included button. There is a16mm through-hole for it above the motherboard in the
middle of the chassis.
Radiator/ Fan Mounting Holes
If you are mounting fans to a radiator with the chassis in between, the 1 1/2” screws need to be used
because of the thickness of the steel. Please see diagram for different mounting options below.
1 1/4”
1 1/2”

Fan and Radiator Mounting Options
240mm Radiator with two 120mm fans
280mm Radiator with two 140mm fans
360mm Radiator with three 120mm fans
