I just ordered a D8000 from Coolcases.com
http://www.coolcases.com/cases/D8000_s-m_p2.html. It is a modified CompuCase LX-6A19 (same as Antec SLK3700) with the fan grills punched out.
I suspect the reason no case manufacturer does this is because it is illegal. It probably causes the case to fail the FCC's EMI tests. Actually, it may be illegal for Coolcases to even do this mod, but I'm not complaining. It would be nice to know how to fix the EMI problems without causing noise from the interference with the fans. Anyone know how to do this?
