Alright, here's the best advice I can dish out for now....
{1} Okay, you'll want to buy the Retail version of Windows, whichever one it may be. You'll spend another $20 with the assurance that you can move the OS to a new build or if upgrades are made. Trust me, it's worth the extra money.
{2} Lose the Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive. Seagate HDs are notorious when it comes to poor quality control, meaning that their HDs are a POS . I suggest Western Digital or HGST, as they're the two best rated when it comes to HD reliability.
{3} The PSU (EVGA 500W 80+ Bronze Certified ATX Power Supply) is okay, but I'd try to go for something that's 80+ Gold certified. The brand you chose is good, but I'd also suggest you bump up to 550 W in the event that you want to perform upgrades in the future.
{4} You may want to purchase a third-party CPU heatsink/cooler. The ones that come stock with Intel aren't very good.
