I build also to same case Windsim setup and used pSU of windsim powering 2x120mm case fans and one 80x80 fan blowing to Ioniboard. I think there should be adequate ventilation.
I will next look to add wireless card to board and do some wheels with wireless receiver.
And i also need to finish all these wheels i have been building…make second improved version of BMW M8 wheel and have them done with Q1R what i will put to Simucube.
Bad thing is that i just saw BMW M4 GT3 model and Porsche RSR wheel model i also want to start to build
