The first time it is without doubt daunting, there are a few of us on here that have done quite a few now and you still worry if the two torx on the front panel will come off ( there is a work around if they don't) and then if the three motor body torx will come out and then what is the state of the board in the motor and the rest and finally and hopefully the magnets aren't cracked.
Still when you plug it in (laid on the floor before you put it all back together I may add
) it's a great feeling when it spins into action.
