The 5.12 expansion lets you use the 500W GaN with your k3.93L… it also increases the maximum graphics card length to ~234.5mm (from ~179.5mm).

Use just the 500W or a 250W along with it for 750W, also 2x 250W would still be possible. The case grows from 360x60x182mm (=3.93L) by 55mm to 360x60x237mm (=5.12L)...

Not only are both configurations (3.93L and 5.12L) hard to beat in terms of density, but you can switch back and forth or "right size" your build with even more expansions… like Flex-ATX or SFX(-L). Please watch the introduction video to get a better idea of what I mean
;)


This build video is also worth watching… be quiet! Pure Rock LP and 6600XT Challenger ITX for scale.





There might have been some confusion and so I moved the original post (which was about the k4.32L) to #5

original post (k4.32L):

My most recent case project, born the moment I first saw the 250W GaN PSU from HDPLEX (at a time where AMD can't deliver a worthy replacement for a 7 year old R9 Nano).












First time I did powder coating myself... and now I want to do a small production run. Maybe ~100 units? 2-3 prototypes before that?


The goal is to make use of the possibilities outsourced manufacturing will give me, but keep it simple so:
  • keep the design only base + cover
  • one more bend on both 200mm sides (of the base)
  • partially removed bend, to better fit the graphics card
  • venting holes in the base
  • keep the outer dimensions to 360*200*60mm (=4.32L)
  • 1mm galvanized steel

Let me know what you think. What kind of venting pattern should I use?

Nicely done! Looks really good. GaN are still too pricey for the wattage you're getting imo.

Any thoughts on venting patterns? I like RV 7-8, but over the entire cover it would be costly and where I'm looking it doesn't scale so much with order volume... Another downside is recirculation of hot air. Good RV 7-8 placement only over the fans would be to configuration specific and look a bit too "functional" :/



RV 5-8 is cheap and with a 6,5/7mm drill anyone can re-drill the holes needed. Intake of fresh air can be prioritized, airflow directed and instead of everything beeing equally revealed a focus point can be set (notice the 6,5mm holes among the 5mm holes? ;) ).

The downside is that re-drilling is almost a must AND the threads on the base will have to be made afterwards (placed individual RV 5-8 specific).
EDIT: Oh and the edges can be sharp depending on where they cut it.. XD

I had the possibility to pass on the RX 6600 without a loss and get the RX 6600 XT Challanger ITX for 430€ (Amazon Warehouse)... Even though the whole motivation behind the k4.32L was to not rely on ITX size cards. Navi 23 is just toooo good to only have a cut down version of it and I coudn't get the ASRock card out of my head! 😓

Yes I could have made the k4.32L fit the RX 6600 XT Fighter but I don't like this model because the memory modules have diffrent thickness thermal pads to make contact with the heatsink ... and the whole heatsink is a joke. WHY don't they first make use of the space there is @ 17cm before stretching it out to 20cm..!🙄More cheap fans and plastic shroud than actual heatsink!

Anyway...
I have ordered 5 k4.32L in December (without a cover) with delivery mid January. And than I made a 3.93L version (360x182x60mm) for ITX size cards and ordered 2 of it. I will have to see whether the k3.93L is even possible (ordered it without graphics card opening).

The only k4.32L (V1.0) and one of the two k3.93L (V1.0) was/is used in two builds now. Online I didn't have much interesst,. niche within a niche? But since it's just a hobby I'm happy to slowly pass on what I have and make room for revisions/other projects. Yesterday I powder coated the base of the first k4.32L (V1.1) ... the cover for this one will be optimized RV5-8 from 1mm alumimim. The other 4 I haven't touched yet because I think someone might want one to custimize himself or as a base for another project or open air? But slowly I'll finish them too ...



self-clinching standoffs ;)

4 Pin PWM extension that comes with the Kaze Flex Slim is ideal for PowerSW/PowerLED ...

Really like the symmetry of the case!
Is the plastic film we see a duct for the GPU fan?


It looks very nice in black!
What is this blue riser, any link to it?
Thank you, no the plastic is from the packaging. I left it on while I was moving the card around alot.

I found the riser on eBay and bought 4 of it at the time: https://www.ebay.de/itm/255507355206 another seller but it must be this one (I use the 18,5cm one).

I think I found the perfect (console style) solution... the k4,32L still has it's advantages, but for me the k3,93L is perfect and can make for a sensible/efficient/silent build.

...and expand! 3.93L (4.97 ... / <6L):

- CPU heatsink, 43mm
- Graphics card, 2,5-2,75 slots 179mm (227mm ... /~270mm)
- single HDPLEX 250W GAN (Dual HDPLEX 250W GAN ... / Flex-ATX)

I'm open to other venting solutions with the extensions. What I have now works perfectly in the 3.93 configuration, but maybe not with the extensions!
The graphics card opening should now be at the perfect size to only reveal the shroud of the card.

I will design a 4090/SFX-PSU expansion if someone want's it XD

i think perfect for me is 6L 340*260*70 with 47mm CPU cooler, Flex PSU (with 80mm fan), GPU up to 255mm 2,5-3 slot (like 3070ti KFA2 1 click-oc, Manli 4070 Gallardo),

That's 6.19L, but OK? A Flex-ATX and the KFA you mentioned would(~should) fit into the k3.93L at 5.75L ...
