Trust me, there's people out there throwing together budget builds for old people that don't want to drop $45-50 on a new 80GB SATA HDD with more space than these old foggies will ever use lol. Much cheaper to spend an extra $5 on the DVD drive to get a SATA and pickup a cheap HDD like yours. In fact, I might take one off your hands at some point
Use USPS flat rate boxes, they're like $8-9. Wrap them in a little bubble wrap if possible and stuff in some packing peanuts from your next newegg purchase.
