About the IDE Floppy Drive Power Pin Connector

"Hey! My name is Kyle Hodge and today I am going to be explaining to you how to un-install and install motherboards. Over here we have where the IDEE cables are plugged in. This machine has ID hard drives so they are plugged in here. CD Rom drives are plugged in directly behind it and if a floppy drive was installed in this machine, it would be plugged in here to the drive port. Right here this is coming directly from the power supply straight to the motherboard. It is a 20 pin connector and in the newer PCI Express Motherboards, it is 24 pin connector. On top of these things, you should note 9 screw holes that keep the motherboard seated properly into the case; one of the top left corner, another one in the middle and another one in the top right corner Then in the middle one on the left,another right there and another far right and on bottom, one hidden behind these cords, one underneath right there and one on the bottom right."
