I found a laptop and a desktop on Craigslist for 155/175. I don't care about mobility so that shouldn't be a factor. I just hate going to the library to print out my essays. I need something that can write essays, steam videos, do some light gaming (Cs:Go/Minecraft), and won't lag a lot. I had an ancient pc in the past but it broke down so I don't have that much experience in cpu speed and ram.
The Desktop has 8gb ram installed and its $175
