Build your own PC from scratch

When you build a computer from scratch you have the ability to choose exactly the type of configuration you want and tailor it exactly to your own needs. Unfortunately, there are lots of things you need to take into account, such as computer component compatibility, which can make the whole process very confusing to say the least. Tech Village are here to help. In this article we are going to show you the importance of choosing the correct hardware. Over the next few weeks, our series of guides will help in choosing hardware for your next computer build project.

If you going to build your own pc from scratch, then you surely need to know have a budget aside and know what you are going to spend. There are different computer types, each one giving you different advantages based on what your application is. When you start with low performance computers, they are ideal for use for web browsing, office use, e-mail checking. These machines are usually very cheap and don’t include powerful components, just enough to help you run the most basic applications. Middle range computers are those that provide you with a little more processing power, which means that they will allow you to play some games, and cab also run multiple applications simultaneously as well.

For those that need a lot of processing power, they should go for the high performance computers. These can be used for a lot of things that are memory and processor intensive, such as audio and video conversion and editing, intense video gaming, 3d animation rendering etc. Such computers can be quite pricey initially, and it’s easy to understand why, but these computer build usually have enough power in them to last a few years longer than the lower scale desktop computers.

Before choosing the type of computer you need, you should try and learn about each component you should include in your own device. There are lots of components out there, some of them external, but only a few are really needed for your computer to function properly.

Desktop Case:

Before you start buying components, you need to consider the case, as all components sit into this. It will determine how many expansion devices and internal disk drives will be inserted into the unit. Its size will also be dictated by how large the mother board is. For example, an ITX case, suitable for Intel Atom processors is extremely small, and some of the regular sized ATX boards will take 5 cards and maybe have extra memory slots, so larger desktop PC cases are required.

The motherboard:

This is basically the place where all computer parts/computer components are tied to one another, this is the unit where all expansion cards are connected to, such as graphics and sound cards. All data flows through the motherboard, so next to the CPU this is an important piece of computer hardware. This is the central area that provides you connectivity options such as Bluetooth, USB ports, WI-FI, SATA ports and memory cards among others. So the size of the motherboard basically determines how large your computer will be, but also how many expansion cards, hard drives memory you can add to your computer. It’s needless to say that the type of motherboard is crucial when you create a custom PC, so you need to choose it carefully.

The processor:

This is widely regarded as the brain of the computer, as it carries all the processing related tasks that you perform in applications or games. When choosing a processor you need to know that faster is better, and the more cores it has, the better. If you don’t need a lot of processing power, you can go for a slower processor which will cost a lot less, but if you create a computer built specifically for gaming, then you do need to get the best processor you can. The PassMark site has a great table with processor bench marks and components

Random Access Memory (RAM):

This is the place where your computer stores the data that will be next required for your CPU. It’s short term memory, meaning all is lost when the computer is switched off. This memory has a faster transfer rate than that of hard drives, so it’s ideal to have this transfer data to the processor, over the hard drive.  Generally the more RAM you have installed on your computer, the faster it will go and the more applications or games you can run at a single time. However, speed of memory is also a determining factor, with higher memory speeds, transferring data at faster rates. This is also true in the case of virtual machines, as they also need a lot of RAM in order to function properly. Most motherboards come with support for large amounts of RAM, and you can easily add more in the future via expansion slots on the motherboard.

Graphics card:

Also known as a graphic processing unit, this one is more like a processor that was specifically created for handling everything related to graphics. Some motherboards come with integrated graphics solutions, which might be more than enough for standard computer usage, but gamers and people that use computers for something other than the office suite want dedicated graphics cards. Depending on the amount of RAM and processing power they can provide, these boards can become the most expensive component in a computer.

Power Supply:

A computer won’t work without being connected to electricity. The power supply is the component which gives enough power to the motherboard and all the other cards you have installed, so it’s crucial that you get one which gives you as much clean power as possible, especially if you have power hungry components such as a dedicated graphics card or powerful processor.

Hard drive/SSD:

A good computer is nothing without a place where you can store all your data, including the operating system. There are multiple types of storage options, from a normal hard drive to a more powerful flash storage option known as SSD. There are advantages and disadvantages on both sides, but you always need to remember that the more you have the better. Choose an SSD for storing important data such as the operating system and your sensitive files, then add the other files to your HDD. We will have an article about storage devices in the next few weeks.

These are the main components that you need to integrate in your computer. Yes, you might also want to add additional components as well, such as a card reader, optical drive, WI-FI board and many others, but it mainly depends on what you are using the computer for.

Operating System & Application Software

When you have built your own computer kit, you will need to decide on an operating system. This is the software that boots up when you switch the computer on. There are many tyoes of operating system, with multiple versions of each such as Linux Ubuntu, Mint and Debian (Desktop) and CentOS (Servers). Here’s a good guide to a round up of Linux Operating Systems. Microsoft have several versions of Windows from Windows 7 and Windows 8/8.1 and Windows Server 2012. We will have an update on server platforms in the future.

Application software is software you use within the operating system, to get your tasks done. Such as Microsoft office with Word, Excel and Outlook for documents and email collaboration. adobe have their suite for media manipulation, such as photo editing and logo design and other branding tasks.
