Stalled k_ses: dual-slot cards up to 229mm (6700XT) @ <4,4L (brickless / internal HDPLEX 250W GaN PSU)

[k0n]

Happy new year to all,

While waiting on the k4.32L & k3.93L prototypes I can't get a third layout based around the HDPELX 250W GaN out of my head:

For longer than 197mm cards I'd change the layout to a sandwich style... here the PSU no longer dictates the maximum CPU/GPU-cooler clearance and when focusing on the Noctua NH-L9 and dual-slot cards you could have a PowerColor RX 6700 XT Fighter @ under 4,4L!

Personally I wanted to have 2,5 slot 197mm over 2 slot 229mm, but actually a undervolted/underclocked RX 6700 XT Fighter should also be plenty silent and is cheaper than my used ASRock RX 6600 XT Challenger ITX. MAYBE there would be more interest in something like this? Please let me know...

Hey!
I'm very interested in the same concept from December 2022
Did you get any other thoughts regarding that concept since this have been posted?

The latest is the baseplate for sandwich/classic layout.

It's probably to late into this generation to focus on the 6700XT Fighter. Sure there will be other cards that will fit, but I wouldn't want to miss out on a potentially great 7700XT just because of 1-2mm.

The sandwich layout would need three separate sheets anyway so I thought I'd make a 'baseplate'/spine for now.

would you consider one more option for low profile gpu too but not sandwich type thou. .. perhaps without the PCIe riser/extension cable

I looked into the classic riserless layout (using an LP card) but couldn't really beat the k3.93L and there are already a couple options around that size (4-5L).

And then it is already in a range where a full height card + SFX PSU can be done.

Also I'm in love with the format of the base k3.93L and it's thinness (60 mm)...

See my current case im using: https://smallformfactor.net/forum/threads/proteus-a-quiet-yet-cool-4l-prototype.18211/
if you ditch the top fans you can get 2.5 slot support for still under 4L, while have 500w to play around with.

@Starficz I know about your project... I'm one of the Likes on your post

The first time that I skimmed through it I thought of only one 250W GaN and that you probably would encounter problems with the ATX ports colliding. (My k4.32L at that time similary had one 250W GaN next to the board but because of console layout it could use the gap between board and card for it's ports. A gap sandwichlayout wouldn't give you.) And then I saw two 250W GaN...

Liked the 3D cramming (which ports of which PSU can be blocked) dedication to 500W, <4L and countersunk screws.

My k3.93L does a little bit of that.

It's probably to late into this generation to focus on the 6700XT Fighter. Sure there will be other cards that will fit, but I wouldn't want to miss out on a potentially great 7700XT just because of 1-2mm.

And has solved this issue. Expansions and diffrent covers are "easy" parts that can be replaced at any time. You are able to always right size your build.

Also there is this party trick of mounting a monitor. For ridiculously small footprint and short cable runs with accesible I/O.
