The first question you need to ask yourself when deciding on buying a computer, is what you need it for.
Buying a home PC is, in a way, like buying a car. What is its primary use going to be? If you are buying a machine to just browse the internet and use for social media and communication, then you might want to opt for a lower end machine. And here is where the second question comes in. Do you want a desktop that is fixed in place, or do you want the flexibility of a laptop so you can move around the house or even take it out of your home so you can use it while on the move?
If you are planning on using the machine to service other needs, such as a media station, then you might want to opt for a home server which has several ports that allow for data sharing and storage across several platforms.
If you want a gaming rig to play computer games on, then you need something that packs a much bigger punch in terms of processing power. You would also need something that has a gaming specific graphics card, as well as a good cooling system to keep the machine from becoming overloaded and breaking down.
These are all questions that you need to ask yourself first. It would be useless to buy a lower end machine only for your kids to try and overload it by playing games that stretch the memory capacity and ultimately shorten the computer’s lifespan.
Once you have figured out exactly what you will be using it for, you then need to think of physical limitations. If you only have limited space, then you might want to opt for an all in one desktop where the computing components are actually built into the monitor of the machine.
If you have a lot more space, then you might want to opt for a traditional tower and wide-screen monitor configuration.
