Components in Suitcase?

[panthro]

Do you think its safe to pack some pc components (HDD, CPU, GFX, RAM) in my suitcase? I live in the UK but work in Australia and I want to buy them here and take them with me as its much cheaper. They will be in the original packaging and wrapped in all my clothes.
Safe or not?

Cant take them as hand luggage, already got an SLR + 3 lenses and my laptop to take onboard. Cheers for the advice
