Can these components be put together to form a half-rack (10inch) width enclosure?

@HughCannon_2673667 As far I can tell, even using only the 2 outer parts (without the middle) will be to wide for a half-rack. If you use a slicer to remove a couple of cm from both parts it might work, but might not be recommended.
The bottom holes won't fit anything properly and you will need to stretch the mesh panels to make them fit.

Hello my friend ide like the aspect of this has is i hould love more 3.5inch drives anyone knows if is possible ?

@RogerioFiguei_302402 As far I can see, its not possible to add extra 3,5 inch drives in the current formfactor. I’ve tried adding a extra U as an extension, but rigidity and vibrations seem like an issue to me. Since I have no need for extra driveslots, the development for the extension got forgotten. For more drives, a redesign from scratch might be the most structional solution.

@StevenTh I think maybe with 3u will be possible the case looks sick I love it!

Started to print this. Its my first serious print, but from what i already printed so far, i see your tremendous effort you put into it.
Seems like the fan mash (STL-file) is not the same as the (gcode) file. STL file seems to be "the wrong" file.

@DennisWinter_2339270 good to hear you are making progress. The stl itself is indeed a massive plate where I applied some slicing adjustments. This way I didnt have to design the mesh :) Added benifit: you can chose the meshpattern and fill density, if your slicer supports it apparently.

@StevenTh yeah, definitely a good option.
Unfortunately creality does not allow to see the sliced model. Also I couldn't make the top and bottom layer to 0mm so you can see the mesh. Definitely an issue on creality side.

This started out for me by just wanting a short 2u Nas.
Finally bought a printer because someone recommended your project. And now I am digging deep in the rabbit hole 😅
Had to make adjustments with blender for the USB front panel screws.
All is still bleeding edge for me. Could not reimport it into prusa. The switched to orca slicer... A multiverse of options :)

I just got the panels to be printed.
Cheers

Printed in black with white front/rear panels. I used a mATX board with sfx power supply so I had to modify a little bit and move the main board all the way over to the right side with P/S on the left. I'm using 2 2.5" SSDs as well as an m.2 nvme for storage. Just waiting on the final front panel to print!

Using approximately 1.8 kilograms of petg, I had a nice server rack with 20% infill. I applied kapton tape under the processor. I made a small mod for graphics card support, but I cannot share it because these holes are normally reserved for PSU. (edited)

@StevenTh As everyone stated; We also need a full size power supply. Is it possible to do this with a few edits?

@DogukanSahil I've tried to make it fit in a 2U format, but a ATX power supply has the same height as 2U. The only way I see possible is by making it a bit heigher to 2.5 or 3U. Since the PSU is also wider, it doesn't fit anymore with an ITX motherboard and 3.5inch hard drives.
I've tried many variations, but I haven't found any combination that is self carrying, fits all components and still fits into a 45cm network rack.
Another option could be a picoPSU/power adaptor, but I haven't got any experience with those.

Will the fan of the power supply be in direct contact with the roof or is there some space between? Might it be a possibility to turn power supply by 90 degrees to ease air flow?

Very well designed case. You invested more brain work in the concept than big suppliers. Great Job!

@Holger_383318 Hi, the fan of the PSU should have about a cm off clearance for fresh air. Since it only needs to pass a minimal amount straight threw the PSU and back out, I haven't experienced any issues with it.
Due to the height restrictions of 2U, I don't think you can rotate the PSU 90 degrees, unless you ommit (a part of) the floor and/or roof which is needed for structural integrity :)

Thanks for appreciating the work!

Hey @StevenTh

Currently building this and love it. Awesome work too! Going to see what I can design for extensions and add-ons. (edited)

I'm wondering how difficult it would be to redesign this to accomodate 4x HDD if we went 3U instead of 2U.
That way, we could probably also fit a non-low-profile GPU to the build. Maybe.

The one thing keeping me from ditching my current QNAP over a custom built TrueNAS system is the price of a decent case with enough room for my disks.

Any chance you have F360 files for this? I could take a stab at a remix for my needs.
Another "good" option would be to print a separate one as a JBOD case.

@OlliErinko_814853 If the length of the case would stay the same, I think you only would manage to add 1 HDD slot in height in the current layout (26mm per drive, 2mm clearance top and bottom for airflow). The extra U in height opens up possibilities to mount things to the roof, but it hasn't been designed for those loads.
Concerning the GPU, I would not trust PETG when running something as a latest gen GPU AMD 7900/ NVIDIA 4000 series in such an enclosure :).

The more interesting route to go might be a 1U expansion unit with 3 (theoretically 4 should be possible) HDD slots next to each other and no roof. Then 6/8 slots might also be possible by adding more 1U boxes underneith the base unit. Cooling might become the problem then, but something like a couple of Noctua NF-A4x20-PWM might fit.
I suspect there a not many mini ITX motherboards around with more than 4 SATA ports, but a HBA might be a solution. (edited)

@StevenTh I've got a couple of rolls of ABS and ASA that I intended to print this out of, so temperatures shouldn't be much of an issue. As for the GPU, I won't be running anything too recent, only enough to provide better transcoding than Intel QuickSync does, while being recent enough to support H265.

I want to make this lol, but the requirements for me would be having 4 3.5in bays:(

@AhnneCognita Thats looks awesome already! It is nice to be able to use a full atx powersupply.
I had trust issues as well in the beginning concerning the stability :) I found out that the best way to get rigidity in the structure is by adding overlapping parts, like the ssd mount in my build.
I’m currently also working on a new roof part for my design that adds an extra 1u and 3/4 extra 3.5 inch drives and/or pci bracket. To be continued!

@AhnneCognita hello my friend your project looks very nice will you finish it ?

Ill try to remix it, but my Skills are Bad.

have a NZXT H1 Build standig around, and i tought i could fit i in my rack :D
ITX Board, SFX PSU.

A new TFX powersupply is only 45 to 65 € if it's the only part that needs to be changed 😉 Just a thought 😜
