The bundle includes a retail CPU (comes with stock fan), as well as a stick of 512MB RAM. It has a 275W PSU.
No, it doesn't have built-in wireless. You'd have to buy an add-in card or a USB adapter.
Realize that the mobo in it will not support a Core2Duo CPU, and that is does not come with a hard drive. You will want to add at least another stick of 512MB RAM to it, as well.
