How to use

Install the chosen Micro-ATX or Mini-ITX motherboard and mount storage to the dedicated 3.5" and 2.5" bays. Position the PSU in the preferred mounting slot (front, sideways or bottom offset) and secure it using the provided brackets and standoffs; an ATX offset bracket is included to allow longer GPU installation in specified positions. Fit the GPU and use the supplied anti-sag bracket to maintain alignment. For cooling, install fans or a radiator according to available space—note that a bottom 25 mm fan reduces allowable GPU thickness. Remove exterior panels to access the interior for cable routing and maintenance; the bottom dust filter is removable for cleaning.

Recommendations

For best airflow and compatibility, plan component heights and GPU thickness before installation: if you intend to use a 360 mm radiator or a thick bottom fan, verify GPU clearance and consider mounting the PSU in an alternate position to maximize space for the graphics card.
