Wee Weasley Welshman,
If you like, I can collect the parts for you, and have them for your next trip to the U.S.
The easiest is getting Mobo, CPU, RAM, HD, and DVD+/-RW, since you can just about fit all of them in the Mobo Box. (The Optical Drive might not fit.) Monitor and Case are usually what I tell people to buy where they live since they are bulky.
Take Care,
Richard
