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).
