Thanks for the advice. If I decide to bring it with me then I will get a hard suitcase to put it in and wrap it up as tightly as I can.
What I am trying to find out is if many people have done it before and is it safe? I know how bags can be thrown around at airports!
I will also look into UPS and other delivery companies to see how much they charge. I have got a decent relocation allowance of 8000QR which is more than enough for me and I already intend to add some extra bags to bring on the flight with me.
My desktop cost me almost £1000 two years ago so I do not intend to buy a new one, not to mention the fact I cannot afford a new one!
