So you're thinking about building a gaming computer from scratch? Well, I can explain a few things to you that will help you on your journey. Desktop/gaming rigs use a lot of energy, so don't freak out when you see next month's electric bill. Assuming you have a good amount of money, I'll tell you how much the items cost and what sizes you should buy. I'll list these items in order of what you should look for first. First you will need to purchase a case, this is one of the cheapest items on your list. Most cases are the same, they just vary in size, airflow, noise, number of drive bays, front ports, cable management, and appearance. Depending on what you get, it could cost you between $75 and $125. Once you have the case, we can proceed with the important goodies. Secondly you will need a processor (CPU), this is the brain of your rig. Since this will be a gaming computer, you will need a very expensive CPU. The third element will be a motherboard, which will connect all the other components of your computer together. It is the basis for everything, for example: USB ports, the number of expansion cards you can insert (such as video, audio and Wi-Fi). You can find one that fits a good gaming PC for around $200. The fourth will be your random access memory, or RAM for short. It's like your computer's short-term memory. It stores data that your computer needs to access quickly to help your programs run faster and help you run multiple programs at the same time. Remember that this is a gaming laptop, so it has high performance, which means you will need a lot of RAM. I repeat, lots of RAM! Most high-capacity RAM cards have 4 gigabytes of space and are sold in sets of two for around $80. The fifth will be your graphics card (GPU), which is particularly but......half of a card ...... g, the price of a power supply could be $175-$350. Items like thermal paste or extra fans or water cooling parts to prevent overheating are very smart investments. These items listed are just a portion of the major factors to consider when considering building a computer from scratch, regardless of what you will use it for. You will still need to purchase a monitor, mouse, keyboard, webcam, microphone, and speakers if you haven't already obtained them. I hope this guide helps you on your journey to the computer of your dreams. Just look at the prices, view the ratings and use common sense when shopping. If you don't feel confident building it yourself, try finding a friend who does or try hiring a computer specialist to build it cheaply. You'd rather it be built by someone who knows what they're doing and have it work perfectly, rather than get confused and accidentally fit the pieces together.
