Can i sell my computer for this much and buy a new one?

i have a imac from 2007 that has a failed power supply and hard drive and i want to sell it for 1200 (the original price) on ebay so i can have the money to get a gaming laptop, no ones bought it yet and it’s been a week, what should i do
Update: i didn’t say the power supply and hard drive were failed on the page, i wrote on ebay that it’s in perfect condition
