512 is gonna lag a bit, better to have 1gb
Definitely go router IMO cuz you'll have a seperate IP address for each pc. Not sure bout switches.
Don't forget the cost of the OS, make sure its a single purchase with a multiple pc license. you don't want to get cracked for installing a single license edition over multiple pc's
First of all, yes, you'll need 1GB of Ram, but don't worry that Value Ram will do.
You also want a router, smartest networkign device out their, and yes, Linksys is good brand and reputable. If you have a problem, they will take care of it. (you sound deciently knowledgable about computers, youll do fine setting it up throught he manual).
Also, about CS:S, You really cannot notice a difference with the AA setting on or off (and thats from a machine similar to the ones your putting together, not mine). Also, you may find people play 1.6 more than CS:S, around here source is hated, I miss 1.5 with a passion.
About the server....If this is a brand new business, you're always going to have to be upgrading to the newest games, especially if you are going to stay on the top of your class. An expensive but good solution to the server, would be a dual intel xeon setup in my opinion, or maybe the AMD opitron, but if never worked or heard much about them. The MB for this dual settup will be expensive, but remember you arn't buying a video card either, and you MAY need registered RAM ( A pain but I dont know...).
Last reccomendation: About where to put the $100, in to a GT, or 64bit system.
I would definatly say get 6600gts. Like I said, you will need to upgrade. When this happens, theses card will work pretty good in the new systems.
Final notes:
A) With those cases, get like 3 different colors, it will make the setup look cooler in the cafe.
B) I am not sure if those cases lock the drive bays, but you may want to consider having the drive bays ALWAYS locked, as to limit security risks with the custumers, when they ask for a game, symply come over with the universal key, open - insert - lock. And you are done, your target audience will love to mess with computers, beware.
