What!!!!???? The Gigabyte B360M-D3H does not have an old-time parallel printer port! Get the ports right! Too much port! Hiccup! Perhaps the 15-pin VGA connector above the DVI connector was mistaken for a 25-pin parallel port? This article should be corrected because it does a disservice to Gigabyte.
But for me, the B360M-D3H has a most wonderful old-time 6-pin PS/2 keyboard/mouse port, which means I could use my most wonderful best ever made IBM Model M 101-key clickety-clack keyboard with spring-loaded never wear out keys, and type really fast.
A VRM is a Voltage Regulator Module which takes whatever voltage is most common in the motherboard and converts it to the much lower voltage needed by the CPU. A VRM is not perfectly efficient in doing this conversion, hence the heat produced due to the inefficiency. It's nice to have a VRM with a passive (no cooling fan) heat sink, to keep its operating temperature down.
