You have NO IDEA how much it sucks to sell on ebay. I was trying to sell my last notebook on ebay and it took way over a month, thus killing the value by a bit.
Learn from my mistakes:
1) First off, DONT offer buy it now unless you're ready to have to start the auction over and over again. People "get their accounts hacked" and go through and end tons of computer auctions all the time. It happened twice to me, each time, costing me the amount it costed to post. Ebay refunds the after sale charges, but not the posting charges, meaning if you use exposure add ons like "bold text" or "special position posting" stuff, you're out that money.
2) There are a group of people out there who try to scam you via escrow.com. This happened to me once. Escrow.com ended up getting hacked, and so I went through all the escrow stuff on THEIR OWN WEBSITE, only to find that it was all done through a hacker who was trying to get me to send out my laptop before recieving money. Escrow.com said on the page that they had recieved money from the buyer and to send the laptop, then right before I shipped it, like, a few hours before, I get an email that says "ATTENTION DO NOT SHIP!!!" from the real escrow reps. They fill me in on the "hack". Thanks escrow.com for the great security.
3) Paypal is NOT a secure way to recieve payment. Check paypalsucks.com and all the other sites to find out the truth about how Paypal can empty your account out at any time for no reason, or how they're completely not responsible for your money. Also, if you dont have a merchant account, they take out a large amount of money. Total junk.
4) Many people will try to scam you from other countries. You'll get hundreds of emails from people in "cuba" or "puerto rico" or "mexico" or "china" or "korea" asking you if you'll offer the machine to them. These are cookie cutter emails and you'll soon start getting dupes. They're all just scam artists who plan on stealing your laptop w/false payments.
5) REQUIRE A LOT OF POSITIVE FEEDBACK. YOU'LL GET TONS OF PEOPLE WITH 0 BIDDING! NO GOOD!! Theres a reason why they have 0. And why they had just registered last week. They will try and try and try.
Theres so much more to be aware of. What is important is that you state your boundaries, stick to them too. Dont accept paypal from anyone who doesnt have a LOT of positive feedback. Don't waste your time with people who make you offers from other countries.
Oh and good luck! Hope that helped!
