For example if the PC costs me: 500$. I want to pay it for 12 months without just paying every component. Is there any website that does do that?
Option 1: Credit card. Pay on your own schedule
Option 2: A prebuilt from some place that does financing. This $500 system might cost you well over $1,000
Option 3: An envelope and patience. "Finance" to yourself, saving a little bit every week, until you save up enough money for the whole system at once.
