No, most new hard drives use Serial ATA or SATA connectors.
E-IDE is a legacy connector that was used on every motherboard before SATA came along. It allows connection to CD/DVD as well as hard drives.
Install the motherboard first. The drives will have wiring harness to connect to the motherboard.
A Molex power connector is a 4-pin power connector found in most computer power supplies. It is used to provide power to large internal drives like hard drives and CD/DVD drives. They are slowly being replaced by SATA power connectors, which are easier to install can cannot be inserted incorrectly. They should not be confused with a Berg connector which is much smaller and is used to power floppy drives. The molex connector is used for IDE drives
USB ports enable you to attach USB-compliant devices The NIC enables you to attach the computer to a LAN or a WLAN The parallel port enables you to connect devices such as printers and external drives
Floppy connectors are used to transfer data between a floppy drive and a computer via motherboard, in order to use a floppy disk. They are very similar to IDE cables, but are a little smaller, and are exclusively for floppy drives.
Because you might drop the drives on your motherboard while installing.
Drives are linked by cables called SATA cables, these send data through the motherboard
An IDE cable connects a hard drive or CD drive to the main board of the computer.
Everything is connected to the motherboard. Everything other than hard drives and disc drives would be directly on the motherboard.
A motherboard bundle typically contains not only the motherboard but also contians the hard drive, RAM, CPU, optical drive and disk drives. Optional extras can be added to meet your own requirements such as graphics cards.
The SATA connector on a power supply is to supply power to SATA-based hard drives. It is not to be confused with the ATX plug that is to give extra power to the CPU, nor the PCI-e power connectors that give extra power to certain video cards. It is unexpected to find a SATA style connector on the motherboard.
SATA, or serial advanced technology attachment, connects the motherboard to hard drives and optical drives. This cable is inserted into the SATA slot on the motherboard.
