Well now that the new MBP's are out I've decided to sell my current Alienware desktop and I'm not sure how much it's worth. Could you guys help me figure out a price to sell it for on e-bay or craigslist? Specs: Athlon 64 X2 4200+ 2.22 ghz 2 GB OCZ RAM Radeon X1800 XL 256mb 80 GB 7200 RPM Seagate HD I also have an unopened 150 GB Raptor HD. How much would that increase the value of my computer if I put it in? Should I put it in my current machine or just sell it alone on e-bay? Thanks in advance. EDIT: I also have a 19" Viewsonic CRT monitor that I could sell with it along with my Logitech G11 keyboard and G5 laser mouse. Everything in good condition.
