Looks as though I'm better off just purchasing a new machine when the time comes and leaving it at that.
Like I said, when the time comes, have a look at ibuypower or cyberpower and utilize the forums here at TR, they're full of very knoledgeable people willing to offer help/suggestions. I hate discouraging people from building their own computers (I love building computers), but I also realize that there is a certain level of knowledge on the subject needed before building a system. More than just knowing what hardware to buy. Buying a computer from ibuypower or cyberpower is going to get you a good quality computer (better than dell/hp/etc) that you will be able to throw some upgrades into yourself. Thats how I got started with my first computer as a freshman in college: I added more ram, then new power supply, then new graphics card, then new OS, then I built my first computer from scratch, and the rest is history. The physical act of building a computer is much easier than its made out to be, a little reading is all you really need to get started.
System building is really a dying art if you ask me, with all the tablets and laptops becoming more and more powerful, less and less people need/want desktops. Its really a shame, computer tech is such an interesting and constantly growing field, its very addicting. You just dont get an appreciation for the hardware inside a laptop or tablet, they rarely get opened up to reveal their inner working parts, much less be able to upgrade/replace those parts to any significant degree. I've spent too many hours to count (and probably more hours than I should) reading sites like Tech Report, Tomshardware, Hardware Secrets, Anandtech, XBitLabs, etc. I just can't get enough, who knows maybe you'll get hooked just like I did/am! (One can only hope)
