I love used parts. i-7 860 2.8ghz motherboad, two hard drives 8gigs ram case powersupply all for $100. I bought my gtx 1050ti for $150 on newegg. So I'm in around $250 and I'll just add in an extra $25-$50 for my wifi card, keyboard, and mouse that I didn't actually spend because I got them for free. So $300 max for a mostly used rig. :-)
