Seattle-based Isilon Systems files with the SEC for a public offering that could raise as much as $86.25 million.

The company was vague on what it would do with this money. Other than repaying about $6.2 million in debt, the rest will go to "general corporate purposes."

I wrote about Isilon last November in this article. "I think we could be the next big company in Seattle," Chief Executive Steve Goldman said at the time.
