Thanks for the replies.
It took me about 50-75 hours to do the schematics and layout the components on the board. And about 250 hours to do all the routing.
After I have sold my remaining PCBs on Amibay, I will release the project files so you can do more group orders yourself. Or continue developing the project if you wish. I wasn't planning to be the sole provider for the PCBs anyway. I'm more interested in doing new hardware.

Yep
And I bet your remaining stock will go fast.
@all
ATX motherboard is being developed right now and should be ready relatively soon if all goes well.
