When we think of a computer, one of the most important and functional components that comes to mind is the motherboard. You can call this the heart of the machine and it is from here that the rest of the components such as the CPU, RAM, keyboard, ports etc. receive power and are able to connect to each other. If the motherboard of your computer is not able to function smoothly, you'll realize that nothing else can go right because man or machine, the heart has to be strong. This is why it's important to get the correct motherboard for your computer and finding the right one can be a daunting task for a layman.
First and foremost when choosing a motherboard, make sure its compatible with the processor be it an advanced micro processor (AMD) or an Intel Processor, because the slots that connects the motherboard to the processor and vice versa should match each other perfectly. Everything that connects to the motherboard such as hard disks, sound and graphics cards, storage devices etc. are managed by the motherboard and are usually inbuilt in modern computers whereas the older models had them connected via slots to the motherboard.
The processing speed of a computer on the other hand is entirely dependent on RAM or Random Access Memory. If you ever find your computer speed frustratingly slow, it's time for you to upgrade your RAM because power hungry applications such a 3D games, video streaming, Adobe Photoshop etc. require a whole lot of RAM. The larger the RAM the smoother your programs will be. RAM however is only a temporary storage device because the moment power is turned off; all information stored in it will be lost.
Once you have everything you require in your customized computer, the last but not least will be the computer casing that makes a modern day computer look the way it does and not a mass of bits and pieces of steel and cable entangled in a frenzy. So what type of case are you looking for? A mid tower, a full tower or all in one unit? Whatever the size, almost every computer casings have accessible sockets for USB ports, microphone and headphone jacks installed in the front for easy accessibility. The major differences are in the size of the case with the larger ones providing more space for the addition of hardware upgrades in the future.
We wouldn't' be normal if we did not go for the aesthetics of the computer casing and next to functionality this is what you should look for. Modern cases can be customized to suit your tastes and can be found in various colors complete with LED light displays and chrome plating while the latest is transparent computer casings where everything inside the computer can be easily viewed like a glass house. But black I think is still the most popular color and preferred by most as otherwise every time we change our home or office color schemes, we might have to change our computer casings as well.
