In September, 22-year-old Joseph J. Brice pleaded guilty.
The Spokesman-Review reports he'll get credit for two years already spent behind bars.
The investigation began after Brice nearly killed himself in a blast his family called an experiment gone wrong.
An FBI investigation found Brice had posted YouTube videos that honored Islamic Jihadists and a tribute to Oklahoma City bomber Timothy McVeigh. They also say he agreed to help Islamic fundamentalists bomb Americans.
Brice's lawyer, Matthew Campbell, said the plots were just jokes and the result of poor decisions, not actual intent to harm anyone.
