3000GB is it really 3TB or typo mistake which means only 300GB?
Now moving from 500GB to 1TB HDD. Wee.....
That means more games to install, setup, configure and troubleshoot.
I mean Game Server 1TB hdd not client.

For client computers, I only need 160GB Hdd atleast per pc, I no longer need 300GB hdd(the times when i do manual games updates

tedious job indeed).
Im using one of the game server system mention in this thread but sorry Im not going to tell which one.
(but definitely not the diskless type).
Most games are setup by me and my collegues/friends.
When talk about game server software and system(not the diskless type, that is something Im not familiar with

), it all depend on who setup for you.
The game server software if you get it direct from the manufacturer, contain nothing except a blank game menu interface. It all depend on how you add games yourself into it or the person or people who help you setup the game server software and even hardware, add games for you. Sometimes they themselves already have a large games install into their master game menu server copy hard drive.
Sorry no posting of the games that I have. Except its consider not much except it take up 400GB+ of space. It could have been more but because server hard disk dont have so much space. Some were deleted.
Thats why now going into 1TB hard drive.
Some members here mention about cdkey changers problem, well for one, some game server or even cafe billing/game server combo have cdkey builtin into their system(but please, its not always perfect for certain games which dont rely on registry). In that case,
1) you made your own cdkey changer.
2) pay someone to made one for you.
3) strangle your friend/collegue to made for you.
4) pay someone online to made one for you.
Some note about game servers using hard drives. Its best that the mapping hard drive is separate from the game server os hard drive itself(that means two hard disk, one for server os etc, one for the mapping drive for games).
Mention about combining two network cards into one in windows to increase the bandwith. Well, I for one never see the second network card blink as madly as first network card in windows even when the server is stress to the limit.
So the second network was taken out. So we need one powerful gigabit network card only.
As for billing software, we cant said one billing software is better than another one. No billing software is perfect, it all comes down to which billing software satisfied your needs or cafe needs.
Talk about maintaining cafe, now the trend is try to prevent getting infected by virus/trojans. Not arguing about who can crack your billing cafe/game server. Forget that, once your cafe computers infected by virus/trojans, think how much downtime you need to troubleshoot or fix your computers, how much earning you would lose when your whole cafe was shutdown just to troubleshoot/fix virus/trojan problems. Now economic so bad, cybercafe earning is more important than anything else.
No bonus, might even get paid cut

Thats all for now.
BTW, deep freeze isnt that all mighty as before. Some virus/trojans specifically attack deep freeze protected system.
so now deep freeze is a preventive system(not 100%), just like other preventive system in the market.
