Hi Lanparty. There is no harm getting the www.lanparty-computers domain, but I agree with others regarding the fact that if your site gets popular, the owner of lanpartycomputers.com could create some headaches for you because most people just don`t naturally type the hyphen key if they read about something online. Many use Google when typing a name, which is good for you since your site will almostt surely pop up to the top.
For any site that takes credit cards or PayPal, I would recommend a dot com. Unless it is a charity (.org), people just expect a dot com in my opinion.
I would think a bit out of the box and use something much shorter. That will be better anyway. Something like LANpartyGear.com. Tell people what you are offering if possible.
Hope that helps,
Andrew
