This system was built to give my son his first experiance in gaming for when he went to kindergarden! He is a light online gamer playing World of Warcraft, Marvel Heroes, League of Ledgends. Also, Learning games online on pbskids.com. The CPU is a dual-core and gives solid performance for what he needs. 4gb works well for his needs and the Rosewill RANGE has a solid feel for such a small case and my sun loves the look of the glowing Led Fans in his room.
