Thanks for confirming. I don't think you need to disassemble your PC to replace the IO panel. I'll looking more into it when the new case arrives.
Also, holding the power button for 5 seconds shuts down the computer and you can always unplug it also, so I have never used any reset switch. So I guess to me, I won't miss it. I like the case design (I've built one before in this case), so even though this issue should be fixed and should not have happened, to me it's something I am willing to live with, since no case is ever perfect. Some have design issues, some have quality issues (thin paint, crappy sheet metal), some have heat issues, etc.
