Will mining bit coins work?

[nothingk322]

Hey everyone assuming I don't have to pay for electricity would it be worth it to buy a fully built cheap computer off craigslist and turn it into a bitcoin miner? lets say something like this for $80 CAN.

- AMD phenom ii x4 965 quad core processor @ 3.4 GHz
- 8 GB ddr3 ram
- gtx 550 ti 1gb graphics card
- around 1.5tb of storage with Windows 10 Home
- all held in a fractal design R4 silent case, with 3 case fans
- Corsair cx500 power supply
