Finally, I have received my second hand dell PC.
I bought it from ebay around $120.
Moreover, I need to change the hard disk and add ram.
Now, I have a new NAS and JBoss server.
I have written a simple game today.
This game is to show how to generate a Random Number in C#.
I have seen how powerful Windows Vista Graphic function.
It fully uses GPU to render graphic.
So, I suggest you a new powerful graphic card before installing Vista.
That's good, finally MS did more things on security.
It can't login by administrator.
Save us more problems.

I have moved to my new home for around a month. Finally, I have a connection. I don't know why the ISP took so long to get the connection!
