Beast of a build on a tiny $300 budget I put together with a LOT of hunting and luck on deals for my little-brother-in-law's first ascension. I ended coming in a bit under budget, I might add $25 of red LED strips to hit the budget; or maybe I'll go a little over-budget and get a ~120GB SSD if I can find a good sale instead.
RAM was sourced from a pricing error at Staples, HDD was sourced as a hand-me-down from a retired rig
I scored the GTX 770 on Craigslist for $150, and just before I left the guy's house he unexpectedly handed me a 3dvision2 kit that he meant to include in the listing.... Blew my mind, and I sold it on ebay for $85 ($65 after fees and shipping). Video card out of pocket dropped to $85!!
The i3-4160 also came from Craigslist, a mother listed it as punishment for her son's grades (He bought it to use in a build and was never able to install it). Another crazy steal that saved a ton of money
I planned on a used Z87-G41 first (~$60) but found a refurbished Z87-G45 on newegg that matched the red/black theme he wanted. Because of the CPU and GPU savings, I decided to splurge on it because I was already so underbudget.
The PSU came from a newegg sale + $30 mail-in rebate
The case came from a sale + $10 mail-in rebate
The two coolermaster fans were from a sale + $5 mail-in rebate for a 4-pack, and I decided once again to splurge on two red LED fans to continue the red+black theme since I was still under-budget at this point.
The retail on this build comes to just under $600, so all-in-all I paid less than half price!
EDIT: Just got back from a monitor purchase on Craigslist! Got a 23.6" Samsung S24D390HL for $20!!!!! These deals just won't stop coming! It has a small scuff only visible when lighter colors are behind it, but for the price I don't mind (and I hope he wont)! Photo added, but I can't figure out how to edit the parts list to add it :/
