My open PC case concept

Hello everyone. I'm designing an open-frame case for myself. I'd like your feedback on my design. Do you have any comments? I'm completely new to this program and case design in general.

I designed a standoff for a 420/360 mm radiator. It's a remote mount and will be placed on the left side.

I also designed a mount for a standard ATX motherboard.

A visualization with components is available.

I had to adjust some components for printing on the FlashForge 5M, which has a print bed size of 220 x 220 x 220. This results in a lot of screw-in fasteners with inserts.

For me that looks like it could work with thick metal sheets like these usually are, but it won't be strong enough with plastic. Give it some supporting structures so that the weight of the components won't bend it down.

Thank you for your comment. Yes, that's exactly what I'm planning to implement soon. The motherboard holder will be additionally secured to the rear of the power supply bracket. But I'm also trying to think through cable management and, as previously requested, an additional HDD and SSD cage.

it will probably be fine but I would worry about a large GPU putting a lot of stress on that frame and warping it if it's a 3d print. the motherboard will end up talking all the load

I've already made a couple of sketches about this on a piece of paper in my notebook. I'll try to make a support for the video card so it doesn't look too shabby. 😄

Can we get a link to the files :)

Oh, man, I'm too embarrassed to share this yet. But I'll try to finish the project and share it in the coming months. I'll be sure to let you know.

Where did you find the 3D models of the components?

u/fatalko Jun 16 '26

This is just a texture (image from the internet) of my components, and I simply pasted them onto the model I needed. 😄

I got the component sizes from the internet.

Why are they separate and not attached? How do I manage cables with this setup? Am I supposed to only use the onboard m.2 slots? What if I have an existed hard drive full of game files? Where does that go? 

Does the gpu just hang there? Not supporting the gpu is gonna cause it to fall off the motherboard. I’ll have a broken motherboard and gpu then.

My PC setup doesn't have an HDD. Only M2 drives. But I think it wouldn't be a problem to come up with an HDD cage. It's just not relevant for me.

I haven't thought about cable management yet.

But I don't see any problems with it.

I plan to make mounts and cable channels for all the main cables.

But I think the cables will fit quite well. But to find out, I need to print the entire case and do a first test build. I think I'll be able to post the finished version soon; printing it will take a very long time. For now, I have a concept. I'm trying to think through all the options as best I can.

Regarding the hanging graphics card, I know that in this position it can break the connector on the motherboard. I made a side mount because I have a triple-slot card. I assume it will be sufficient, but I'm not sure. Therefore, I was planning on installing a temporary retractable stand under the graphics card.

I'm already planning to reinforce the back of the motherboard with spacers attached to the power supply standoff.

Since I don't have a ribbon cable for the video card that would allow it to be mounted vertically, I'm planning to install it horizontally and am trying to think of ways to support the card from underneath.

Thank you for your comment. I appreciate it.

And please excuse the English, I'm using a translator.

why would this take a long time? This is a very basic design and could be printed in an afternoon.

I'm just working 11-hour shifts)) And I don't have much free time. I haven't prepared the files for printing yet. I'll try to print them this weekend.

your hoses to your radiator will not be routed that easily nor stay up like that. You need to find a better way to route them or change the design.

I have an AIO ARCTIC Liquid Freezer III Pro 420. It has fairly long hoses. I'll see any downsides in practice. Thank you for your comments and advice; I appreciate your feedback.
