Rosewill today announced the FBM-Z Series, a new lineup of three microATX mini tower PC cases designed to simplify the building experience without compromising on style or performance. Each model ships with a pre-installed power supply and a tempered glass side panel, giving builders a strong, display-ready foundation from the moment they open the box.
