I'm happy to see a new thread started for a new C4.
I really like the slotted top panel, but I think it looks a little strange with the M1 v6 style side panels. I know
@dondan has already said he thinks that slots on the side panels would make it look too industrial, but I'd still like to see a render. I think the case would look better with the top slots carried through to the side panels.
As for the front, I really like the plain front with the power button, and any IO on top.
I was wondering if it might look better if the front panel wrapped around to the sides a bit further, so the join between the panels on the side was aligned with the start of the slots on the top panel (A continuation of the first slot down the sides of the case).
I bought an Ncase M1 v6 from the first run last year, but I need to build another PC up towards the end of this year, so I'll be following this thread closely to see how the C4 turns out, and keeping an eye out for the redesigned A4 too.
