How to Build a Compact Desktop Computer

Compact Computers Can Be Perfect Additions to Home Theaters.

Compact computers, also known as small form factor (SFF) computers, are quickly gaining popularity due to their increased presence in home theaters. There are plenty of component choices, so finding the perfect parts for your compact computer is now easier than ever. If you're familiar with assembling a standard PC, building a compact PC should pose little trouble. The primary difference between building a standard PC and a compact PC is dealing with the cramped case, because fitting the components into these cases can be a little challenging if you're used to working in spacious mid-tower or full-tower cases.

Things You'll Need

• MicroATX computer case
• MicroATX motherboard
• Processor
• RAM
• Hard drive
• Optical drive
• Power supply unit
• Graphics card
• Non-magnetized screwdriver

Instructions

1. Choose and purchase the components for your compact computer, including a case, motherboard, processor, RAM, hard drive, optical drive, power supply unit and graphics card. Ensure that the components are all compatible with the MicroATX standard. Some cases include a power supply unit while others come in a bare- bone configuration that includes the power supply and motherboard. Some motherboards include on-board graphics, although these graphics generally do not deliver the same high performance offered by discrete graphics cards.

2. Place the motherboard on a flat, non-metal surface. Insert the processor and RAM into the motherboard sockets. If the processor has a heatsink and fan, install them onto the processor.

3. Install the hard drive and optical drive in the case. If you purchased a separate power supply unit, install it in the case. Insert the motherboard in the case and use the non-magnetic screwdriver to attach it to the case using the included standoff screws.

4. Connect all case cables (including power, reset, and any others) to the motherboard. Insert the hard drive and optical drive into the case and attach them according to the case instructions. Connect the cables between the drives and the motherboard. Connect all required power supply cables to their respective slots (including motherboard, fans, and drives).

5. Power on the computer and check to ensure that the system boots properly to the BIOS. Close the case and install the operating system.

Tips & Warnings

• Use an antistatic wristband to avoid transferring damaging static electricity to the computer's internal components. Before inserting the motherboard into the case, look closely at its layout. If you are familiar with the motherboard's layout before it is in the case, you'll have an easier time locating hard-to-find ports when it's installed. After successfully booting your computer, turn off the computer and use cable ties to neatly organize cables. A messy cable configuration typically prevents proper case airflow and cooling.

• If your processor has a heatsink and fan, make sure to plug in the fan to the motherboard before powering on the system. When inserting components into the motherboard, be careful not to bend the motherboard excessively. Don't force cables into slots. If you're not sure if you're using the correct cable, check the motherboard manual.
