Having a smaller, mini-ITX motherboard, affords a new path to exhaust heat from the "top facing" fan on the new Nvidia Geforce RTX 3000 series cards. Diagram with both ITX and ATX motherboards with the 3080 and 3090: This assumes using a "standard" layout i.e. not sandwich. What do you think?

Hey, any idea on what's the minimum bend radius that can be achieved on the tubes coming from the radiator of the Kraken X63 (or really any CLC)? I'm working on a design that might involve a pretty agressive bend on the tubes. Something like 40mm from the radiator surface to the PSU surface, any...

Yes, I believe you both are correct. I only had a cylinder head bolt at hand :)

Haha I only know this one! It's what I have found in my region so far:

Thanks for the suggestion!! For joining the profiles at 90 degrees, what size extrusions do you have pictured? I think my 20x20 beams wouldn't work because the axial hole fits a M6 screw, however the channels are too narrow for an M6 head from what I tested.

Haha thanks! Just one more question: do you only drill a ~3.5mm hole for the screw to go through or do you also drill a hole for the head to accomodate "inside" the profile? If that makes sense.

Thanks a lot!! It just never crossed my mind to make through holes... Do you find it hard to find appropriately long screws after that?

Given the 20x20 profiles I'm using, when slotted in the PSU sides are ~4mm away from whatever the makerbeam is attached to, if that makes sense. So at first no the PSU wouldn't sit on anything.

Sounds good! I'll try to get some rubber washers and slot it in along the "short side". By the way, about the spec: if we slot it in by just one side, maybe that wont provide enough support? I wonder if the three holes in the drawing are supposed to be the minimum needed for mounting the PSU

Absolutely! It requires some serious fine-tuning to make it slide in and not rattle afterwards. Too little pressure and it feels loose, to much pressure and it feels like you are about to shear the screws from the psu face right off while you slide it in :P Another possible problem is...

Playing around with aluminum extrusions (Makerbeam) and 6-32 screws. Apparently they sort of fit together if an M4 washer is added to the mix. Could potentially be interesting for cases based on extrusions, for mounting power supplies and ssd's...

Thanks! As far as I understand it was made out of whatever scrap metal there was at hand on my friends shop :P I checked back on the design file and I think a better formulation would be: Slots (in mm) = (width = 5.058, height = 12.5, pitch_X = 6.558, pitch_Y = 14) That should be a bit more...

Just got a prototype of one of the slotted versions back! There's just something about how structurally sound it looks in (absolutely overkill) 2mm thick a36 steel: Slots (in mm) = (width = 5.5, height = 12.5, pitch_X = 7, pitch_Y = 14) Next step is trying on a more viable material e.g. 2mm...

I appreciate the empiricism. I'm awful at Mechanics, what would happen if there was a force parallel to the support profiles (i.e. going into the image), and the brackets were screwed down? Would the fan move at all?

Oh yeah, at our somewhat philosohical dsscent into fan hole spacing I didn't quite think about the appearance of the screws. I guess here's a point where custom hardware (i.e. black pan head allen screws) is an option or maybe even a must :P I will try to prototype a version of the slotted...
