I built this pc as a gaming pc for my sisters Christmas present, so it had to be a tight budget build. Almost all the parts I got on sale from black Friday, eBay or Craigslist and they all worked fine except that I had a defective cpu which took a lot of my time to figure out and eventually replace..
Cpu: Obviously this cpu is a no brainier for $85, especially for a budget build like this one!
mobo: cheap is I could find for the mobo. I'm sure it will work just fine.
GPU: I did a huge amount of research on these and figured out that the best possible deal on eBay for price to performance for under $100 was the 7870. Especially when I won a cheap auction and got it 13$ cheap that the average price point. Everything works great on it and it came with the box with everything. eBay is the best place for gpu's for budget builds. This thing blows away the 750ti and its half the price. haha
HDD: Got this gemstone of Craigslist for $5.. Its slow as crap but it holds 320gb and thats what matters most.
case: Dirt cheap micro atx from a good brand. The case had decent cable management and it feels sturdy. I really like this case, considering I rebuilt this computer 4 times trouble shooting the cpu...
psu: Whats not to love? EVGA is a good brand. this thing is heavy and feels quality. Cheap after rebate and good reviews, also 500 watts is just perfect.
Monitor: I got this off craigslist for $10. Yup, why buy new when you can get something that works for way cheap. Budget builders need to take time and look at c list and eBay everyday for the right moment to bid or call on a product!!!
Overall, this build was frustrating to work on because of the defective cpu, I was just that one in a thousand I guess. My sister loves playing guild wars 2 on this thing and apart from the hard drive it works really fast, but its amazing how much of a difference having a legitimate hard drive will make for the speed of your pc.
