OK, I wanted to spread the word also on this forum about several issues with CoolerMaster HAF-X case. It seems that HAF-X cases have issue to burn mobo or firewire chip on it. I experienced same issue. Motherboard is Asus P7P55D-E, Corsair 850W TX and HAF-X case and my Firewire chip is burned on second power on. On first power on I didn't connect LED illumination for front vent so LED was turned off. After I turn off PC and connect LED light, on my next power on I have burned VIA Firewire chipset.
Cause of this problem:
I disassemble front panel and it is visible "design flaw" or "assembly flaw" on our HAF-X case. Red wire that goes to LED switch has broken isolation because of sharp pins from front panel motherboard on which front firewire is connected. In other words, when front firewire is connected to mobo and when LED switch is turned on, LED switch wire directly touches one sharp pin from firewire front connector and there we have short circuit causing firewire chipset burnout on mobo.
Those two picture will explain it.
Clearly visible broken isolation on red LED wire:

Visible broken isolation and sharp pin from firewire that touches broken isolation:

The question is now who will be responsible for this? I think nobody, we will isolate this wire with some tape and continue with our business, right? I get NO answer from CoolerMaster customer support for Europe. !!!Shame!!!
