Prototype J-Hack Pure Mk2 APU case

[maxdfw]

This is not a true mini-dtx motherboard. It is mini itx that is extended. Mini-dtx has two pcie slots.

They removed the second pci slot for a sound card, it's still DTX form factor.

What do you guys think about doing a mixture of 3d printed and sheet metal design?

3d printed design can give you more customization options while the sheet metal ensures it is sturdy.

Sounds good!
As long as the 3D printed parts are of good quality, have a look @CC Ricers's experience in this post and following: https://smallformfactor.net/forum/t...type-3d-model-now-available.10927/post-170006

I've been a fan of this route for a while now and it is what I'm doing with my personal projects.

IMO 3D printed parts (FDM) straight off the printer do not look good. I've seen it argued that they have character or a "brushed metal" like surface but I feel that is trying to sell it on its flaws. Finishing makes it look a lot more professional and removes the layer lines and flaws that make it look like a prototype. Sanding / polishing help a lot. Acetone smoothing might give good results for ASA/ABS. I'm going to be sanding & painting my parts.

I have no idea what costs & time finishing 3D parts would be for manufacturing a case, but if the case makes prominent use of 3D printed parts then I think it should be considered.

 

[Windfall]

Do you mean cutting sheet metal panels and them holding them with 3D printed corners.

 

[Thehack]

3d printed parts will be unseen. For example the rear panel, or internal screw points.

 

[NateDawg72]

Then in terms of customization options, are you thinking something like several options for rear panels?

If it's not visible, doesn't affect stability and provides a benefit, I'm welcoming this. ?
I also agree with @NateDawg72 that such parts should get polished a bit, even if they're not visible.

I may have to do a pre-order run when I'm ready. Looking like Spring 2019 for a small batch.

Haven't exactly nailed down the size, but it'll likely be a bit deeper to address some of the design concerns from the last batch. For example, some people were concerned the rear IO can be pushed in.

Spring 2020?

Ah yes. Meant 2020.

248 x 66 x 200; 3.27L.

 

[Sean Crees]

Yes, I have also been thinking about that. The issue with a second set of tabs or screws is that it requires additional screw holes, which breaks up the aesthetics a bit.

Adding a tab is definitely possible if we're willing to add screw holes to the top panel.

Mk2 is a bit larger than Mk1.

If the problem is just with the panels collapsing inward, couldn't you just have a tab poke through a small slit in the side panel. Not so much that its sticking out, but the tab sits flush with the exterior side panel. It would break up the aesthetics slightly, but perhaps less so than a screw head would.

Interesting concept here. I like the use of the LP GPU being sideways. If I'm reading the thread right would you be able to do a brickless build with an LP GPU if you used the UHP-200-12?

Yes. It'd be supported for personal for those who are mod experienced.

Not so much that its sticking out, but the tab sits flush with the exterior side panel. It would break up the aesthetics slightly, but perhaps less so than a screw head would.

It is also a matter of need more bends to give it some stiffness. The aesthetics will look pretty good regardless as the black screws do blend in.

@Thehack - Awesome, where would the UHP-200-12 be mounted in the case?

It would be mounted up in front, where the mobo header is using double sided adhesive.

 

[Thehack]

Feature locked.

MOBO: Mini-DITX/Mini-ITX;
GPU: Up to 185 mm length, dual slot, low profile
Power entry: 12 mm 4 pin mini-din support, C6 power entry cutout
PSU: RPS-200 mounting

Fan: 2x 60 mm in GPU config

Final dimensions: 190 mm x 248 mm x 66 mm, 3.1L

UHP-200 feature dropped. Double checked the dimensions and the case needed to be 205 mm deep to accomodate it, which puts it too big at 3.45L.
