The answer is no, if there is no active patent protecting the parts. If there is a patent protecting the parts but a manufacturer of the parts has a license to make and sell the parts, then the answer is still no. When you purchase the parts you own them and can use them freely. But you cannot use them to make a computer or any other device that would infringe an active patent.
