im thinking of buying this bundle http://www.scan.co.uk/mixit/ , number 1 i want, but im wondering weres the heatsink/cpu fan because dont the cube's have there own heatsink/cpu fan
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.
