In this guide, we'll be talking about how to build a computer, from what materials you need, to the safety precautions you'll need to take. It may seem like a daunting task at first, and there should be plenty of research done into finding what components you want for your PC, among other things. However, building a PC is a very rewarding experience, so don't feel afraid!

  • Reasons to build a computer:
    • Easy & fun!
    • Educational
    • Cheaper than retail computers
    • Fully customizable, you choose the parts you want
  • Before you begin, you should have...
    • A clean & open work space
    • A helper
    • A plugged in, working monitor
    • Patience
    • Computer Parts
    • Some flat-head & Phillips head screwdrivers

Step 2: Precautions & Safety

Picture of Precautions & Safety

First, we need to make sure that the workplace is safe, both to the person working on the computer, and to the computer components themselves.

  • Electrostatic Discharge Safety:
    • Wear an ESD wristband, and use an anti-static mat.
      • If those items are not available, touch an unpainted, metal surface on the PC case.
    • Keep all components in their anti-static bags until they're ready to be installed.
    • Use a clean and open work space.
    • Work on a grounded surface, and never work on a carpeted surface if possible.
  • Tool Safety & Maintenance:
    • Only use tools for their intended purpose, never use an oversized screwdriver for a smaller sized screw.
    • Use proper cleaning materials.
  • Component Safety:
    • Never apply force to a component into a port/slot.
    • Only hold a component by the edges, and never by the contacts.
  • Use patience & common sense

  6. (6th Picture) Locate the ATX power header on the motherboard.
  7. (7th Picture) Line up the hook on the molex connector with the tab on the ATX power header, and insert it, until it clicks into place.

Step 9: POST

Picture of POST
  1. Take the speaker out from the bag of parts that came with the case.
  2. (1st Picture) Locate the speaker header on the motherboard.
  3. (2nd Picture) Insert the speaker connector into the header fully, orientation doesn't matter.
  4. (3rd Picture) The motherboard so far should look like the picture.
  5. (4th Picture) Locate the front panel connectors that are connected to the case.
  6. (5th Picture) Find the front panel headers on the motherboard.
  7. Line up the front panel power connector with the PWR section of the front panel headers on the motherboard, and connect it fully.
  8. (6th Picture) Connect a monitor to the graphics card installed on the motherboard. Make sure the monitor is connected, and has power.
  9. Connect the power cable from the back of the power supply to an outlet.
  10. Flip the on/off switch on the back of the power supply to the on position.
  11. Press the power switch on the front of the case.
  12. Within a few minutes, there should be a small beep emitted from the motherboard, along with the visual logo for the BIOS appearing on the monitor.
  13. If there isn't, go back and revise the steps, making sure you've followed every step correctly. If you've revised the steps, and you've also double-checked your build, but you still aren't receiving a beep or a visual confirmation of a successful boot, check with a classmate or the teacher.
  14. Turn the power supply off, & unplug the power cable for the power supply.

Step 10: Fans

Picture of Fans
  1. Remove the two sides of the case by removing the screws on the back of the case, two screws for each side.
  2. Set the side panels in a safe location, where they won't interfere with the build.
  3. (1st Picture) In the back of the case, there should be a spot for a case fan, above the rectangular I/O shield port.
  4. There should be two arrows on the fan, one pointing along the fan, showing which way the fan will rotate, and one pointing to the back of the fan, where air will be pushed. Orient the case can so that the air will be pushed out the back of the case.
  5. (3rd Picture) Make sure that the power connectors for the fan are closest to the open space for the motherboard.
  6. (1st & 2nd Picture) Line up the case fan with the holes. Use the two screws that came with the fan, & install them in holes that are diagonal from each other.
  7. There should also be a spot for another fan near the front of the case. Remove the front panel by squeezing the 6 black pins that attach the front of the case to the frame of the case.
  8. Repeat steps 4 - 6 for the front of the case, making it so that the fan will pull air in from the front of the case, & push air in to the case.

Step 11: Case

Picture of Case
  1. Remove the graphics card & the power supply connections (VGA & ATX) from the motherboard.
  2. Set the case on its side, so that the open space where the motherboard should be installed is facing upwards.
  3. Remove the bags of various screws included with the case, and sort them via the manual that came with the case.
  4. (2nd & 3rd Picture) Install the I/O shield included with the motherboard into the back of the case, orientating it to match the picture. Press firmly on all four corners until they pop into place. Proceed to press on the sides of the I/O shield until it is installed.
  5. (4th Picture) Remove the shield for the top expansion slot in the case by bending it out, and then removing it.
  6. (5th & 6th Picture) Locate the holes for the standoffs in the motherboard, and line them up with the standoff holes found inside the case. Install the standoffs in the designated holes in the picture.
  7. Set the motherboard inside the case, lining the motherboard holes up with the standoffs that you just installed. Make sure the I/O ports line up the the I/O shield.
  8. Screw the motherboard in by loosely screwing in all of the screws, then gradually tightening each one.
  9. (7th - 10th Picture) Install the power supply in the bottom of the case, with the cables facing into the case, while the port for the power cable faces out the back of the case.
  10. Re-plug in all the power connections into the motherboard that you removed in step 1, such as the ATX & VGA power. If the VGA cable doesn't reach, use an extender.
  11. (11th - 15th Picture) Install the headers for the front panel. Make sure the individual headers, such as the PWR & RES headers, are inserted into their right pins as according to the graph on picture 11.
  12. Install the graphics card into the motherboard again.
  13. (1st Picture) (Only do this step if you have an optical drive) On the front of the case, there are expansion bay slots. Remove the cover for top one, and re-install the front of the case onto the case frame.
  14. Do a test boot. Connect a monitor the graphics card, and turn on the power supply. Boot by using the power switch on the case, and see if it can boot successfully. If not, go back and review your build.
  15. Unplug the monitor & power cable for the power supply, and turn them off.

Step 12: Hard Drive/Optical Drive

Picture of Hard Drive/Optical Drive
  1. (2nd & 3rd Picture) Near the front of the case, there should be a hard drive rack at the bottom. Place the hard drive on the bottom rack, and line up the holes on the side of the hard drive with the holes on the side of the rack, as seen in the 3rd picture.
  2. Install the hard drive screws that came with the case. Install them on both sides of the rack.
  3. (4th - 6th Picture) Plug in the SATA cable that came with the motherboard, into the motherboard, until it clicks into place. Make sure to align the header correctly.
  4. (6th & 7th Picture) Plug the other end of the SATA cable into the corresponding port on the hard drive, until it clicks into place.
  5. (7th & 8th Picture) Find & plug in the SATA power cable (on the power supply) into the corresponding port on the hard drive, until it clicks into place.
  6. (2nd Picture) (Only do the following steps if you have an optical drive) There is a rack for larger drives, such as optical drives, above the hard drive rack. Place the optical drive onto the top bay, and line the holes up on the sides of the optical drive with the holes on the side of the rack.
  7. Repeat steps 2 - 5 for the optical drive.

Step 13: Cable Management

Picture of Cable Management
  1. (1st Picture) Plug in the power plugs for the case fans that you installed earlier, into the SYS_FAN headers on the motherboard. For the front case fan, you may have to route the power cable through the back of the hard drive rack, so it may reach the motherboard.
  2. (2nd & 3rd Picture) Organize the cables inside the case, using zip ties. Make sure no cables are touching the fans.
  3. Re-install the side panels for the case.

Step 14: Finished!

Nice tutorial...

btw you could've mentioned some cable management which I don't see here ;)

ryaguy15 (author)Dwargh2015-11-17

Step 11 includes a few instructions for cable management, but we could've expanded on it. Sorry!

I have never used an antistatic mat for building a PC. All you really need to do if you are paranoid is put the PSU in the case, plug it in to the wall (So the case is earthed) then you are good to go.


You dont even have to turn the power on at the wall since ground is always active. The switch is only used with hot/live.

Really and truly an antistatic mat is something 99.9% of people who don't know how to build a PC don't have and is a costly investment

I know you mentioned about an unpainted section of the case, but as mentioned, the case does need to be grounded for it to work.

jantjep (author)Falney2015-11-17

I do not want the case to be the same level as ground but I want the case to be at the same level as my body and the parts that are not attached yet.

Most people do that by using antistatic mat, but that mat does not have to be connected to ground at all.

Falney (author)jantjep2015-11-17

Most people dont have anti static mats. I do not know a single person that does. Also you put the case on your desk. Most power leads are between 1.5 and 2m long which should reach. Especially if you use an extension lead.

Thats a great point! Since we have them at our school we use them as a precaution. The students know they are not mandatory, but for a learning experience we use them along with other precautions to prevent anything from happening. These students are working toward taking the A+ exam, so we try to cover as many different options as possible. Thanks for your input!

Just saying, you could of gotten much more bang for your buck on this OC

ryaguy15 (author)WingraMax2015-11-16

It was a PC build kit that was provided by our school, and the parts weren't of our choice, but we definately could have.

JonathanR74 (author)2015-11-16

Nice Job! Very detailed directions to the build that we did in class.

rpotts2 (author)2015-11-14

Nice basic tutorial. going 0-75 is much more rewarding when you built it yourself, than 0-100 on a Best Buy special.

Oh, and I hate those tiny connectors in step 9. Since I started playing with electronics, I now have enough stuff to make my own block connectors. much simpler to do them all in one go.

WingraMax (author)2015-11-14

Sorry, I meant PC
