"The overall construction and build quality is good and the simple lines and black anodized finish provide a nice background for highlighting all your internal goodies (visible through the large side window). Thanks to its slightly larger size, the m998 can easily accommodate a large PSU, extended ATX motherboard and it comes with 11 drive bays. The two bundled 120mm fans provide good airflow and can be supplemented with an additional 80mm fan on the side window if desired. And if you plan to floor mount this enclosure you will certainly enjoy the optional (included) caster wheels."
