RAM is so cheap these days too! DDR3 RAM, 16gb, for only $60 after rebate! I feel like I should go to jail for stealing :P. I remember when RAM was like $100 for 4gb. Apparently, times have changed and I'm not complaining. Also had to get a SSD for faster accessing times. Ended up with a Kingston V300 SATAIII 120gb SSD drive for a cool $99.
I'm boring with the video card since I had bought one last year when my old one died. I guess this would be the most outdated part in the computer. I've got a GeForce GTX550Ti 1gb card in there. Not too shabby, but not the best either. It works fine for my editing, so I'm not complaining.
To top it off, I bought the Cooler Master Elite 311 case. My old computer was cased in the Elite 310, and I really liked that case. So much so, that I was looking around for it, but discovered that it had been discontinued. Makes sense since it's over 3 years old now. So I did the next best thing, bought its successor. I really like this case, very simple layout and looks nice. Also pretty cheap at $42.50. For good measure, I threw a 600watt Cooler Master Power Plus power supply in there (pictured above).
Overall, I'm very happy with this build. I didn't have any problems with any of the parts and installing Windows 7 64bit was a cinch. So now everyone is happy! My parents have a working computer that isn't giving them problems, and I have a new beast that edits and renders my videos faster! Couldn't ask for anything more for $750 (that's with an *)! I'll give you a breakdown of the parts and prices below, but $750 was a great deal for the build.
Asus P8Z77-V LK - $124.99 after rebate
Intel Core i7-3770 3.4GHZ - $289.99
Corsair 16gb DDR3 1600MHZ RAM - $60.11 after rebate
Kingston V300 SATAIII 120gb SSD - $99.99
GeForce GTX 550Ti 1gb video card - "free"
Cooler Master Elite 311 case - $42.50
Cooler Master Extreme Power Plus 600watt PS - $$39.99 after rebate
Crappy DVD+R drive from my old computer - "free"
So all of this added up to about $750 after rebates, not including a few small parts, a crappy video card I put in my parents computer, and I took the Windows 7 key from their old Dell since they won't be using that anymore :P. Pretty good deal considering, but don't expect to build the same computer at this price. Yours would probably be at least $100 more, if not a little more than that. Now that you're pumped up to build your own beast, go out and get it on!
