This is my first build and it was a great learning experience. Honestly without this website I probably couldn't have done it. I ordered the parts over the course of a month, getting them when Newegg ran specials. The total price for everything after rebates and deals was under a $1000. I already have a Razer DeathAdder for my mouse and a keyboard. I had an extra optical drive lying around and purchased the TV through Newegg. I love pretty much everything about this build.
The one problem I do have is with the cooler. When I first tried a push-pull config taking air from inside the case my CPU was idling at 45 degrees! When I switched it around to pull air from outside the case, it was significantly cooler, idling at around 34 degrees. However, I won't be able to get a stable overclock at all with this cooler, and at the time I purchased it I told myself I wouldn't need to overclock since I got it for $50. Now I wish I had invested in an H100 so I could push my CPU further and will probably upgrade in the near future.
Love the case! It has plenty of air flow and my motherboard temps never go 1 or 2 degrees above the temps I had when I turned my computer on. The Samsung is fantastic, though it does fill up faster than you think. To clear things up I purchased the power supply for $80 when Newegg was running a killer combo.
I also have a 3D mouse, which is fantastic for modeling and editing. If you anybody cads or works in the 3D space, would suggest getting one. You can also use it as a joystick for gaming. I use this for gaming with RPGs and FPSs, and this system can totally handle any game I throw at it with maxed or almost maxed settings.
Update: I added an Intel NIC because I wanted to get a better ping on my home internet. Also, since Logan from the TEK recommend I get one of these and it was $20, I couldn't pass it up.
