Jon showed me how to build PCs. He spent time learning and getting A+ certified and knows more about computer electronics then I ever will. He knows voltages and other terms that I have never bothered to learn. One day he showed me how easy it is to build a computer. Basically you stick slot a into tab b, it’s simple. He had a fancy anti-static wrist band to protect the components, but taught me to simply touch the case before handling the components.
If you want a custom computer get your own computer kit and start inserting the cards. The hardest part is picking the components and making sure that they all work together, if you find some predefined Computer Kits the hardest part is taken care of for you. You can build basic PC or a powerful unit, once you do though, you will find yourself looking to upgrade and add more powerful cards, and being able to install the upgrades yourself will save you a ton of time and money.
