Overview
In lesson 1 we'll cover SATA, IDE, external and SSD hard drives, what features and specs to look for when shopping, and how much you can expect to pay when building your own computer.

The hard drive is where all information is stored on your computer. Be it the Windows operating system, programs you install, or files you download and create on the computer. Everything is stored on the hard drive.

When selecting a hard drive to install into your computer there are two basic features you need to consider. They are the capacity and the speed of the drive.

Capacity:

Capacity is how much data a hard drive can store. Capacity is measured in Giga Bytes and Tera Bytes. 1 GB is made up of 1000 Mega Bytes. 1 TB is made up of 1000 GB. To give you an example of how much you can fit into 1 GB of hard drive space, take a MP3 audio file. The average MP3 audio file takes up 5 MB. Divide 1000 by 5 and you get 200. So 1 GB of hard drive space can store 200 MP3 music files. A 1 TB hard drive, which is 1000 GB can store 200,000 MP3 music files.

The size of the drive you choose is up to you. Generally you should buy the biggest drive you can afford. We recommend at least a 750 GB drive.

Speed:

The speed of the hard drive is determined by the revolution speed of the disk inside the hard drive and the amount of memory cache included in the drive.

The rotation speed is measured in RPMs or revolutions per minute. Most hard drives spin at 7200 revolutions per minute. Faster hard drives spin at 10,000 or 15,000 RPMs. The revolutions speed is important because the faster the drive rotates, the more quickly data can be written to and read from the hard drive.

10,000 and 15,000 RPM drives are expensive and the capacities are limited. We recommend buying a 7200 RPMs drive.

The memory cache helps to speed up the accessing of the information on the drive and the more of it the better. Drives can have 32 MB or more of cache. When purchasing a hard drive, a minimum of 16 MB of cache is recommended.

Solid State Drives

SSD or Flash memory based drives have no spinning disk to store data on. All information is kept on flash memory chips and can be read back much quicker than from a disk based drive. These drives are expensive and have lower capacities of between 8GB to 512GB.

Larger drives are coming and you can expect the prices to drop, but disk based drives will continue to be the most popular due to their far greater storage capacity.

Interfaces:

The hard drive connects to the computer through the hard drive controller on the motherboard. The most common hard drive controller is called Serial ATA or SATA. Sometimes pronounced say-ta or sa ta. A SATA controller's speed is measured in Mega Bytes or MB per second. The original form of SATA had a speed of 150 MBps.

SATA II controllers which are found on all motherboards today have a speed of 300 MBps. Also, SATA II introduced a few new features. The most important is called Native Command Queing or NCQ which speeds up the access of data a little bit more. The next version of SATA will be called SATA III and will run at 600 MBps and will probably also include a few new features.

To get the speed and features of SATA, whatever the version, both the motherboard and the hard drive itself have to support the same version of SATA

An older hard drive controller type called IDE (sometimes called ATA) with speeds that topped out at 133 Mbps is being phased out and will become less available on future motherboards.

For this reason we recommend buying a SATA II hard drive for your new computer.

So when you go to purchase your hard drive or drives, you're looking for... 1. At least a 750 GB drive capacity.
2. At least a 7200 RPM speed with 16MB of cache.
3. Serial ATA II support.
4. If you want to try RAID look for your type of RAID support 0, 1 or 5 on the motherboard.

Build a PC Computer - How to Install a motherboard - All New for 2009 - homepcbuilder.com from Michael Cooper on Vimeo.



Overview
In lesson 3 we'll take the next step to make a computer by installing the motherboard into the case. We'll attach the Intel CPU cooler to the motherboard and connect the cables to the motherboard.

Motherboard Risers

To install the motherboard into our case we first have to position the risers. The risers are designed to raise the motherboard off the back of the case to prevent an electrical short.

The risers are screwed into positions around the back of the case to match up with screw holes on the motherboard. The risers have screw holes in them to allow another screw to go through the motherboards holes and secure the motherboard to the case.

Some cases come with risers that clip into place, in the case and other cases have risers that are built in.

The best way to find the positions for the risers in the case, is to hold the motherboard in place and look for the holes in the case that correspond to the holes in the motherboard.

Be sure to put risers where ever a screw can go through a hole in the motherboard. Its important not to add unneeded risers because any risers that dont correspond to a hole in the motherboard will make contact with the circuits on the back and short out the motherboard.

Once the risers are in place we need to install the face plate for the motherboards external connectors on the back of the case.

Face Plate (rear panel)

The faceplate is included with the motherboard. You may have to remove part of the plate with your screw driver if it covers the connectors on the motherboard. The case will usually come with a generic plate that you have to remove. Press the edges of it from the outside of the case and it will pop out.

Then slide the face plate that came with the motherboard into place, from the inside of the case. Press around it's edges and it will snap in.


Installing the Motherboard

To attach the motherboard, insert it into position and move it to the back of the case, so the external connectors are sticking out the back.

You should see the risers through the holes in the motherboard. Put the first screw in the top left hole, but leave the screw a little loose. This will hold the motherboard in place and still allow you to move it slightly in order to add the remaining screws.

Add the next screw at the bottom right of the motherboard and leave it loose as well. The rest of the screws can go in any order.

Once all the screws are in, push the motherboard toward the back of the case and tighten all of the screws down.

Connecting Front Case Cables

The last step in installing the motherboard is to connect the cables from the front of the case.

On this case there are separate cables for the Power and Reset buttons, and a HDD LED, which attach to pins at the bottom of the motherboard. We could connect them directly to the motherboard, but this Asus motherboard came with a Q-Connector. The Q-Connector lets you plug all of the cables in it. Then you plug the Q-Connector into the pins on the motherboard.

If you have a motherboard from a different manufacturer, check the motherboard manual to locate and identify the pins. Connect the cables with the names facing the top of the motherboard.

This will insure, in most cases, that they are attached in the correct direction. If it turns out that a button or light on the front of the case doesn't work. Make sure the cable is connected to the right pins and try flipping it over.

Most cases also have ports on the front panel for audio in and out, USB and Firewire. Firewire is also called 1394

The audio cables from the front panel connect to a AAFP header on the motherboard. The connector has one missing pin and will only go in one way.

We're installing an add-on sound card in Lesson 8, so we'll wait to install the audio cable.

The USB and Firewire cables from the front panel will go into colored headers on the motherboard. The USB headers are usually blue and the Firewire, red.

Be sure to check your motherboards manual to identify the USB and Firewire headers. The connectors are pinned the same, so it is possible to plug a Firewire cable into a USB header. If you do, the motherboard will be damaged.

Some cases will also have a loose grounding cable. If your case does, remove a screw that holds the motherboard, attach the grounding cable and tighten down the screw.
