Many individuals are daunted by it, but building a computer is simple. Most people that are new to building will end up buying the wrong parts and messing up an otherwise good build. While there are a number of points to pay attention to, knowing what to watch out for and why makes the buying and construction process easier than one would think.
The socket of the processor not only represents how new the design is, but it also signifies that the motherboard must match. Given that the CPU is the most significant piece, it is good to select which to buy and base the rest of the system off first. If the socket of the processor is an AM3+ for instance, the motherboard can only support that socket and an AM3, AM2+ or AM2 will just not fit it. RAM has to stay the same too, but it is easier to match these up. Any type of DDR3 RAM will function on a motherboard that has DDR3 slots, and therefore it is not important to stress over which type of DDR3 RAM to buy to match.
Although most motherboards still support older IDE drives, it is important to make sure that everything is using the modern SATA devices. Any SATA type is backwards compatible, so matching is not an issue, but to get the most speed, one must take notice of the 6.0 or 3.0 rating for both the motherboard and drive itself. The DVD drive can support the increased speed too, but the technology simply is not fast enough to take full advantage and is not necessary.
Some specialty computers will entail issues with getting a suitable power supply, but in most cases a power supply will work for any system build. One scenario is if a computer is running multiple graphics cards, and these need multiple graphics card power plugs to run properly. Even though many of these setups can be rigged to split connections off of one another, they will frequently not supply enough power to keep everything working healthily.
The motherboard-integrated network card is good for most things, but some types of setups will require more robust networking gear. However, if one is building a small cloud setup or server room with a very high speed Internet connection, they may desire to upgrade. Standard systems can still get PCI-E cards that support Cisco GLC-T or any other Cisco SFP modules that could be needed. Money can be thrown away throughout the process if these items are not necessary, and as such it is important to do some research to see if that is required.
