The instructions and illustrations are very straightforward, and the Cube Kit includes the Torx drivers - they are adequate for the job, but if you have your own with conventional handles they will be easier to use. A large flat table, preferably without a carpet then you can do it without a wrist strap, the phone switched off, the children in bed and it is very straightforward -about an hour and half for the timid not having previously opened a Cube (me) and less than an hour the second time, or if cavalier! I had previously upgraded processors on PCI boards, but nothing more. David
