Due to the delays with the HDPlex 250w Gan, the first internal PSU to be supported by the GPU module will be the Picobox 200 dcdc, a somewhat obscure but perfect sized dc module found on Taobao/Ali for $20-40 but capable of powering up to a slightly tamed RTX 3060. It can either be given it it's own dedicated 19v brick, or, share a single brick like a 300w Dell, which powers the GPU and the DeskMini together on a Y-splitter. This is only for advanced users as it will need it's own wiring harness. Rough volume of the case with the Pico, 2 slot GPU and single brick will be approximately 3.6 Liters, and with 2 bricks approximately 4 Liters.
After that I will add support for HDPlex 250w GAN and HDPlex 400w dc-dc together, as they have the same exact hole patterns, so it's the same design. Depending on power needs there are many possible configurations with these modules:
1) Brickless. HDPlex 250w GAN, 12vEPS to Barrel Cable for DeskMini, Midrange GPU such as RTX 3050
2) Internal + Stock Brick. HDPlex 250w GAN Internal for GPU up to 3060ti, Stock Brick for DeskMini, No Y-Splitter
3) Single [BIG] Brick. HDPlex 400w DC-DC Internal, Y-Splitter for DeskMini, GPU up to 3060ti, use Dell 300w brick.
4) Dual Brick. HDPlex 400w DC-DC for GPU up to 3080(?), Brick for gpu, stock brick for DeskMini, No Y-Splitter
Edit: #5) Half height GPU with HDPlex Gan occupying vacant space in dual slot area, total volume approx 2.9L
These are almost plug and play as there is not much custom wiring. Rough volume of the case will be about 4 Liters with HDPlex mounted underneath internally, but ultimately depending on GPU length.
