I posted a week or so ago about a $99 (well, $93) PC I built from scratch from gaming. Had so much fun with it, I decided to set my sights on a $150 budget build. I decided to re-use a lot from my $93 build, but removed the CPU/MB/RAM/Cooler which totaled $43 spent, so that brought my initial starting expenditures to $50, giving me around $100 to work with for my $150 total budget.
Whoo, just had a great pick-up off of Craigslist. Seller has a Phenom II X4 840, 2x8 GB DDR3 1600, and an ASUS M4A78LT-M LE motherboard listed for $60. I offered $50 and he accepted. He had a Linksys EA6350 router and an ASUS Xonar DG soundcard also included in the listing as separate items for $10 each, but I didn't want them. Went to make the purchase and he was a really nice guy, played WoW, and we chatted a bit about the hardware and such. He ended up throwing in the sound card and router for free, which I don't need, but it looks like I'll be able to sell them both on Ebay for around $20 a piece. After fees and shipping I'll clear probably $20 easily as a total profit, so that $50 I spent above should come down to no more than $30.
Pretty insane pick-up for upgrading my $99 PC. Grabbed a Coolermaster Hyper T2 from Microcenter for $8.73 after a price match, tax, and rebate, so that'll sit on top and should handle the Phenom modestly well even with a (very) mild overclock.
Also grabbed a used 60 GB SSD from Ebay for $22.50. So, I'm at around $130 budget now for my entire rig after upgrading from my $99 budget, and importantly, I move from the LGA775 platform (farewell, Q6600!) to an AM3 platform. Still not the newest platform of course, but now I can very comfortably upgrade on the AM3 socket without much issue if I want to, although once I go over $200 for a total system budget I may land in the realm of just grabbing the cheapest used Ryzen 3 I can find, depending on how awful DDR4 prices are.
