The best way to learn is to replace your current computer (that you are using to post in ET, right now) with the new parts, one at a time. First start with the video and sound cards. Then Hard Drives, RAM, CPU, Cooling device and etc. In the end, try replacing the newly updated components into your new case. This shouldn't take more than a few hours and in the end, you'll get hang of replacing it. I think the only tricky part is setting up your BIOS. But of course, if things don't work, you can always put back your system to where it worked last. Other than that google search about building your own computer. Also, just make sure you're grounded to eliminate static elec. from your surroundings. Also, make sure you have the parts that are compatible/capable of working.
