The Mercury News reported today (Sept. 24) that it is selling its headquarters at I-880 and Brokaw Road to Super Micro Computer, which will covert the site to a manufacturing facility. The Merc said it will remain in the building until sometime next year, when it hopes to move 300 news, advertising and administrative employees to a new location “in Silicon Valley.” The building’s sale price was $30.5 million. The building has been the Merc’s home since 1967, when it was built for $1 million.
