I had a good idea for it. It would basically be to build the most compact PC. With a budget of $750US or CA. So, using the normal style of price per dollar and then comparing that to the actual size of the machine, we can calculate a score that gives more advantage to smaller PCs. But as a twist, they have to buy one or more parts from another source that is not Craigslist, and they get two full days, totaling to 48 hours.
