I didn't include a mouse because I don't know of any really good mice for the money. Everything else is great though.
In 5-10 years there will be new sockets and way better cpu's (hopefully) but this system should last you at least 5 years. You can also upgrade this overtime. (you just can't upgrade the Mobo otherwise you will run into some windows problems
)
