Thanks for your reply.Thanks for your feedback! Right now looks like design is still under review by the shop but I'm confident that it's easily printable. I had split the case in order to make it more manageable for printing time.
I was meaning to make 3D printed cases with a sandwich layout for quite some time. Figure there could be a need for cases that would more affordable than the Dan or Kolink cases, if they are fine with choosing one made of plastic.
The Geeek PSU that you mentioned would unfortunately be too long to fit inside this case as it is. It is 170mm long because of the modular connectors, and the attached cables need at least 12mm more room. Not to mention the angled power plug coming out from the bottom, would need 20cm of room there. I know there are some very slim angled C13 power adapters that come from Taobao and I might try those out.
The types of FlexATX PSUs that would fit are 150mm non modular PSUs, with one main exception. The SeaSonic Flex SUB and SUG series. I like these PSUs because their 24-pin modular connector is at a right angle, and it sits within the 150mm length (The M1U is too long being 190mm). It is possible to make custom cable sets that would plug into the 24-pin connector, to make the lengths fit better inside of the case. The only limitation is that these PSUs top out at 300W so I wouldn't expect anyone to throw in a 9900K with a 2080 Ti along with them.
The case's internal height is 182mm. So I'm figuring that a Noctua NF A9x14 fan cmbined with a Seasonic Flex PSU of 150mm with a bracket that attaches the PSU to the fan. The 92mm fan holes are also to be used with various adapters that can fit several PSU and fan arrangements.
More potent power solutions require the use of a MeanWell EPP-400 or EPP-500 with a 92mm fan and DC-DC power board, and those are more DIY solutions if you can manage with them.
I may consider producing a somewhat larger case that would fit a SFX PSU and coolers up to 48mm tall if I think the structure holds up very well without requiring drastic changes to the design.
EDIT: I haven't set a definite price point for it yet but tentatively could be $90-95 without the PCIe riser. It would include acrylic panels and necessary screws. Also I may buy a few of the low-profile power plugs and test them out. These would add compatibility to more Flex PSUs.
I've used one of those Meanwell PSUs in the past. It had a perforated cover though. I guess you can have the same cover for the EPP-500 version too.
My only complain is it's a pity to not have compatibility for "all" of the Flex ATX PSUs. I understand the case would grow bigger but we're talking about the same format and not an entirely new format. It also makes things a bit complicated: this Flex ATX yes, that Flex ATX no, the other Flex ATX maybe.
What's nice about the Geeek Delta is that it's Modular for real. One plug = One cable and then you can make high quality cables if you wish.
I build systems for sale, these little details allow me to create very good looking finished products that I can then take professional photos of.
What kind of screws are you planning for the acrylic side panels? I really like hexagonal screws like these ones that once screwed sits levelled with the acrylic panel. Black or stainless steel.
The price is Ok. I look forward to seeing photos of the prototype.
