Quick help/advice on computers worth

[Sheppard]

Im putting a computer together to run a flight simulator at a hobby shop I used to manage.
Anyways I have no idea what to charge them for the worth of this system. Anyways here are the specs.

Core I5 750
Gigabyte Ga-p55a Ud3
Radeon HD 4890
8GB DDR3 1600
1TB Seagate 7200.12
Antec Toughpower 700W

What do you think this is worth?
Thanks in advance
