Motherboard to fit into cylindrical DIY case

[Atevoh]

Hello i had an inquiry regarding if there is any motherboard that would fit into a DIY cylindrical PC case. The case would be about 7 inches in diameter. I am trying to make a server in the cylinder for a specific purpose and would love to be able fit the components in it. If you guys have any ideas they would be greatly appreciated! Thanks!

See:

You can easily get a 6.7" mini-itx board in that setup.

Not quite a cylinder but you can see how they are packing it.

There are also NUCs which are really small and can fit in that cylinder.

this is just my thoughts what you could maybe do.

13 inches diameter means your mainboard should be small, mini atx should be an option maybe, the reason therefore is simple, you may want to install a GPU and this could cause height issues so you should think about this too.
so i would choose a form faktor like mini atx and than search a good mini atx Mainboard model that i like, and the components that i would be enough for my overall usage intentions.
i hope this thoughts could help you somehow. and if not. you just loose a minute of reading
