As a sentient being it's illegal to list it's price as if you could own it. I could say, however, that to 'employ its services' would cost you around seven big ones.
In simpler terms, you do not own the computer but rather the computer of which you claim has cost you $700
Unless my understanding is incorrect you 'rented' a computer that so which you do not interfere with its workings?
I've most likely misunderstood you.
