The manual and everything clearly says 4 internal 3.1 gen 1 headers, but I can only see 2. It's also supposed to have 2 internal USB 2.0 headers, and I only see 1. I have 2 components in need of a USB 2.0 header as well as my front panel that requires one 2.0 header and one 3.1 header. I also lack one USB 3.0 port for a pheripheral, and I'm looking for a solution to that. Any PCI cards? And where are the missing USB headers?
