Again thanks for the all advice.

I'll have a look at the cost of shipping using UPS, DHL etc. I imagine it is going to be much cheaper taking on my flight and then I'll have it straight away.
I am tempted to maybe get another monitor upon arrival, that way I can careful pack up the box in a small hard cased suitcase, one that it can fit in nice and tight then I'll put fragile labels on it.

Do I need to tell my airline about bringing a computer with me? I can add additional luggage and pay for it on their website but it doesn't say anything about computers.
