Dell previewed the desktop as part of Earth Day at the Fortune Brainstorm conference being held in California.
The small form-factor desktop is 81 percent smaller and uses up to 70 percent less energy than a typical desktop mini-tower, said Anne Camden, a Dell spokeswoman.
She declined comment on hardware specifications, brand name or pricing. Details will be released later this year when the desktop is released.
The desktop, which stands on a holder, will come in recycled and recyclable packaging, Camden said.
