How much would you pay for a Dell Inspiron 545 desktop computer?

I just bought a Dell Inspiron 545 desktop computer. It has 6gb of memory, 640gb hard drive, card reader, 23" flat panel monitor, Intel Pentium dual Core E5400 processor, speakers, mouse, and keyboard. Also has a DVD/CD r/rw optical drive. Just wondering how much it would be worth if I were to sell it. Thanks!!How much would you pay for a Dell Inspiron 545 desktop computer?If you just bought it, it's in new condition still. Look at the retail price and maybe subtract from it according to any blemishes, scratches, etc. that may have appeared on it. If you want to sell it, remember to install a fresh copy of Windows and whatever other software that came automatically with it, because that would factor into the price as well probably.
