How do I Build a Computer?
You should be able to build a pretty decent rig. You’ll also need a case, PSU, Mobo, heatsink, HDD, and DVD/CD drive. Making sure you have compatible components is the hardest part of the whole ordeal. If you’re not interested in/can’t figure out what you’re looking for, barebone kits are a nice alternative. Getting OEM versions of components and software will also help keep costs down.
it doesn’t matter what you buy, it matters that you read the documentation. Do a lot of research, other than asking on yahoo answers. Go to tech sites, and go through ebay looking for parts to see what goes for what price. Decide what you want to use a computer for, and aim for that. Also keep in mind, that you may not be able to afford everything now, but you can add things as you go along. Turn it into a project. Study, study and more study.
