It is very easy to build a computer regardless of what some think. Many individuals will end up running into issues when buying pieces while not knowing if they will fit together or not. Developing a great computer can be very fulfilling, but without some general knowledge of pairing parts together it can be a stressful disaster that deters one from building again.
The socket of the processor not only signifies how new the design is, but it also implies that the motherboard must match. Given that the CPU is the most crucial piece, it is good to select which to buy and base the rest of the system off first. Any other socket apart from AM3+ will not work for a motherboard and processor chip that have AM3+ compatibility. Similarly, the RAM must match, but it is a little more obvious when buying. DDR3 RAM will only match a motherboard with DDR3 slots, but this is particularly common nowadays and one would be hard pressed to build a modern day system with anything different.
Even though most motherboards still support older IDE drives, it is important to make sure that everything is using the modern SATA devices. Receiving the most speed is very important, and as such the motherboard and hard drive should support the 6.0 variant although they are backwards compatible. This only impacts the DVD drive and hard drives, but the speed is mostly essential for the hard drive as it matters the most for system performance.
Most system builds will not have to have a specialty power source, but some will in certain circumstances. One scenario is if a computer is running multiple graphics cards, and these call for multiple graphics card power plugs to run right. Splitting then off or transforming them can work, but in general this is not great to do since it will sometimes not supply steady enough power to keep everything running healthily.
Few setups will demand more than a standard network card, but some will need specialized cards to be set up correctly. However, if one is constructing a small cloud setup or server room with a very high speed Internet connection, they may wish to upgrade. There are PCI-E cards that support Cisco GLC-T or other Cisco SFP modules for regular systems that do not have server quality hardware. Making certain the upgrade is worth it by doing some research is essential to make sure lots of money is not wasted along the way.
