computer build, from start to finish, how long ?

[Jampolo]

Tomorrow i get to order the rest of my parts to complete my computer,
im just wondering how long it will take to build from start to finish ? I've never built a computer before but know a lot of the theory and where to put what part

basically i got from 5 until about 11, can i build it in 6 hours and have it up and running?

cheers

ok thats fair enough, does the manual with the motherboard give you a guide on how to fit it ? (generically)
also i hear people saying that RAM has to go into specific slots? could someone elaborate on this please
