I do not agree with excluding all buying recommendations from this site. If you have a specific problem that need to be solved with special kind of hardware (be it the whole system or just the component), wouldn't you want to ask experts what they think is best. I am not talking about providing exact models or prices or links to product pages. I am talking about giving users general suggestions.
The buying recommendation questions will age, as pointed out by the post above, but so will any question about any hardware.
I think certain types of question that ask for advice of what type of hardware to buy should be allowed. I recently asked a question that apparently fell into this category and was closed, but thanks to the users of this site I got very valuable responses.
