Costs for the components in my mobile mp3 player

Grand Total - $491

You could probably replicate this project for about the same price. You would have to buy a hard drive, which would add around $130 for a 4.5 GB fujitsu. You'd also want video, which can be had for around $20. If you're looking to save some money, you could og with the LCD for $111 (assuming 10 bucks shipping). You could also get a used pentium and motherboard for less. I recently saw a P133, case+PS, and motherboard (as well as other parts I don't want) for $60, so there's $200 right there, bringing the total cost to $278.

Of course, you need to install all the parts in your car, and you need either an external amplifier, or a radio that accepts line-level inputs. You could conceivably use one of those portable-CD player to casette adaptors, or you could get an RF adaptor to run it through the antenna input and use your existing stereo setup. I think that'd be a heck of a good deal...
