Hehe, I was thinking the same. First of all, I am surprised that none of the eGPU housings do have some space for storage drives, either 2.5" SATA or for NVMe cards. But when one is at it, make a bay for the Mini too :). Which also shows why it is so annoying that Apple doesn't just basically offer the Mini motherboard in a larger box.

You could probably build an eGPU box with the same footprint as the 2018 Mini for stacking above it: it should be just possible to fit a small-form-factor GPU in that space. It would be a lot less unwieldy and weird-looking than plunking a normal full-sized eGPU next to the Mini.

The Sonnet Puck pretty much has that form factor (just not a matched case material) but tops out with an RX570 and uses MXM form factor cards so a bit less than ideal.

especially, if the card would be in vertical, there should be place for a full-sized gpu.
