What is this? The tied-down bundle of cables includes, on the other side of the shroud, the standard things I can identify, such as the USB 2/3, audio, LED, etc., but not these pictured. Are they fan controllers? The case has a built-in fan control switch. Tangentially, would this plugged-in metal lamp serve as a ground while working in the case?
