It is easy to build a computer despite what some think. 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 look for and why makes the buying and construction process much simpler than one would think.
The socket of the processor not only signifies how new the design is, but it also signifies that the motherboard must match. The one part that most everything else will be centered around is the CPU, and as such it should be decided on first. AM3+ exclusively will fit a certain kind of processor, and another socket would not work. RAM has to stay the same also, but it is much easier to match these up. DDR3 RAM will only fit into a motherboard with DDR3 slots, but this is particularly common nowadays and one would be hard pressed to build an up to date system with anything different.
In order to avoid any performance or driver issues, it is an excellent idea to use all SATA hard drives and disc drives. Receiving the most speed is important, and as such the motherboard and hard drive should support the 6.0 variant though they are backwards compatible. This only affects the DVD drive and hard drives, but the speed is mostly very important to the hard drive since it matters the most for system performance.
Some specialty computers will entail problems with getting a suitable power supply, but in many instances a power supply will work for any system build. Computers with a number of graphics cards will require the same level of graphics card power plugs in order to run appropriately. 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.
The motherboard-bundled network card is good for most things, but some types of setups will require more robust networking gear. A cloud system with an incredibly high speed Internet connection will need to have a faster form of communication. Sometimes a Cisco GLC-T or other types of Cisco SFP modules can be the solution to bandwidth troubles. It is essential to do some research for the setup first to ensure that the upgrade is worth it before adding in a new amount of complexity.
