"I think I was going for the decent selection of PCs in my hometown, you have no choice which is rather more correct."
By all means make your choice at the store, but make sure you buy online from someone else. The chances are the online equivalent has a higher spec, even if the main part of the model number is the same, or will at least be cheaper, even with delivery. If you get a dud (it happens) and have to return it, you likely won't get an argument from someone professionally obstructive.
