BeamCase is a system theat allows you to create your own case with the combination of 3d prints and Makerbeam XL profiles (or similar 15x15 aluminium extrusions).
Beamcase SFF is a system optimized towards compact builds with good cooling while still allowing a lot of flexibility. It allows the use of large aircoolers like the Noctua NH-d15 and large GPUs. By combining 3d prints and Makerbeam XL profiles the case is extremely customizable and strong at the same time.
The files for sale here include all the brackets to complete a frame in multiple different variations, either as a 2 or 3 slot variation and each of those has different options for the rear IO bracket, with support for a rear 120mm fan with different PSU extensions and the option for a rear mounted full size ATX power supply. (the 2 slot version has clearance for 2.75 slot GPUs and the 3 slot version for 3.75 GPUs slots)
Fan brackets, alternative handles and more can be found on my profile for free.
All frames variations use the same upper rear IO bracket, which comes in different versions. There is the option of a rear mounted 120mm fan and different PSU extension mounting options, as well as a rear mounted ATX PSU (which will limit the CPU cooler clearance). The files also include an empty upper rear IO bracket that can be used to create your own variations. (for example integrated pump mounts and so on)
That upper rear IO bracket is combined with the parts for each version which can be found in the correspondingly named folder. That includes the lower IO bracket, mainboard beams and lower beam replacement, pcie cover, SFX psu mounting bracket.
By default 300mm long Makerbeam XL (or similar 15x15mm extrusions) are used for the length, which give enough clearance for 315mm long GPUs. The length of the case is purely defined, by the length of the profiles, so longer profiles, will give more GPU clearance.
Each case can be customized to your needs with additional brackets.
to make the positioning of brackets easier use these Nut-Positioners.
v5 of BeamCase SFF is a major update, that reworks the entire construction of BeamCase SFF. The core aspects and dimensions are the same, but with the updated construction. The largest part, the rear panel is split, which means the case can now be printed on smaller printbeds with a length of 220mm, like an Ender 3. There are other changes that I will go over in more detail in a video.
Screws:
M3x8mm countersunk screws
M3x16mm countersunk screws
6-32 unc screws around 17mm long for the internal sfx power supply (4pcs)
(and 11-12mm long ones for a rear mounted ATX version)
Nuts:
standard M3 nuts (and potentially with these nut-positioners)
and optionally thin M3 square nuts according to DIN 562 (together with these nut-positioners)
(I am located in Germany and buy my screws here.)
Makerbeam XLprofiles (or similar 15x15mm extrusions using m3 screws and nuts):
4x Makerbeam Xl profiles 300mm long (or other length depending on your desires size)
2x Makerbeam Xl profiles 200mm long
Powerbutton:
The case has a spot for a 16mm generic powerbutton at the back, but other options are possible, with additional brackets.
Cable:
For the internal SFX (or SFX-L) psu you will need a psu extension, the exact length and angle will depend on your setup. There are options both for a screw in type extension and a clamp in style (see video for details).

Print Instructions frame:
The frame parts should be printed in somewhat heat resistant materials, PETG or better ABS. All parts are designed to be printed without supports, but a skirt is advised with the larger pieces.
The frame parts should be printed with at least 4 walls and 35% infill in order to be strong enough.
You should consider shrinkage of the material as the parts have to be precise in order to fit properly. (I use Sunlu ABS and Bambu Lab ABS, I adjusted for shrinkage by scaling everything to 100.5% but some people were able to print it in PETg without any scale adjustments.)
Print instructions outer panels:
The panels have two parts in each STL. To print the fan grill/mesh pattern You first have to press split to parts and then you can select the inner part and reduce the top and bottom layers to zero, this way only the infill will be printed and act as a mesh. You can choose an Infill pattern you prefer, but for good airflow I would choose an infill percentage between 12-18%. (the case in the images uses grid infill as a mesh pattern and infill percentages of 15% printed with a 0.6mm nozzle)
These parts are primarily aesthetic so the can be printed in any material you like (in some rare cases PLA panels can deform with high exhaust air temperatures). In order for the panels to fit perfectly they have to be printed accurately, so ideally consider shrinkage.
Both the 2 slot and 3 slot version require a printbed of at least 220x185mm, which means that everything to print this case will fint on an Ender 3 style printer.
I printed everything on a Bambu Labs P1S which can fit all parts very easily
