*SPAM APOLOGY*
I've decided not to build my DAN-A4 (black) so will be selling it. I'm UK based and it's due to be shipped any day now. UK buyer preferred, may ship to EU. PM me if interested.
Some do, some don't. For example the Founders edition has venting across both slots. As you say it's a chassis standard so not much you can do. If Boil is really worried I'm sure he (?) can choose to take a Dremel to it.
It appears the design it slightly more modular now - as further...
