I think lan party is just the name of the mobo. A lanparty is where everyone goes and plays video games over a network. As long as you have a way to connect to the network you should be fine.
DFI makes the Lanparty series of motherboards which offer special features not found on conventioanal motherboards. Lan parties are open to any motherboard ) In other words, you don't need a Lanparty from DFI in order to play on a Lan party. I hope you get what I mean.
