I am receiving the first feedback from customers of the first batch and I'm glad to hear people are happy with the case.
However, there is one issue I'd like to address: for some reason it seems that some motherboards need to be pushed quite hard against the I/O shield to make it fit.
Today I had a look into this issue and re-tested the cases I still have on stock with all my MOBOs and I/O shields I have available. Three out of four fit almost perfectly, only one was a little bit off and had to be pushed in place.
So I had a closer look to that one to find the root cause: It seems that some I/O shields have a much smaller offset than others. Since I followed the design-guideline from Protocase, using a offset of 0.5mm from case wall to GPU bracket, this might cause issues for some MOBOs and I/O shields.
If you should run into this issue, here is a quick and dirty workaround to make it fit: just bend the flaps of your I/O shield outwards inwards as shown below and everything should fit just fine. For the next production batch planned for end of this month, I'll add another 0.3 to 0.5mm offset for better compatibility.
