Hi, I'm fairly new to PC Hardware so I was wondering if someone could help me out with building a computer, which I'm interested in for both saving money as well as education. It would be a PC for home use (Internet, Office use,etc.) What are a couple quality sites for hardware? What are all the components I would need? (A case, a hard drive, Motherboard w/ processor, modem, sound card, video card??) What are hardware compatability issues I should keep in mind? What about processor slots and sockets? I'm not sure I understand the difference, or how to avoid buying the wrong thing. Sorry, lot of questions, but any help would be much appreciated. Basically, I want to order all the parts online that I would need, and don't have much of a clue what I need or where to begin. Thanks again!
