here is my advice and just to let you know I have helped put on 50 person lans all the way to 150 and I have been to 500 person lans. The most important thing about running LANS is POWER you can damage the building or peoples computers if you dont do it right.

here is what you need:

Power:
you need enough power to provide for 2 plugs per person 1 for monitor and 1 for computer. most lans do not allow anything else like external speakers and things like that that take extra power. Generally you need about 40amps per circuit with one circuit providing power for 4 computers. most LANS require no more than 500-600 watt power supplies for the computer and no CRTs above 17" inches or LCDS above 24" if all of that is met you should be good on power.

network:
generally you have a switch or too depending on the number of people involved. Good switches usually come in 24 or 48 ports. Most of the time you run snakes to central locations basically they are just a bundles of Ethernet cables with female jacks on end and male on the other. you plug the male ends into the switch(s) and leave the other ends for players to plug there own cables into. just make sure your cable runs don't exceed 100m as cat5e ethernet is only rated to go that far. be sure to take into account the players cable as well general rule of thumb 15 feet minimum for their cable. as for swtich speed 10/100 is ok but 10/100/1000 is best but more expensive for a switch.

all thats left is people to show up with their computer and plug in.

hope this helps if you have any questions feel free to send me a PM
