Things to Consider

This case is relatively large (505mm deep) due to E-ATX support; measure your desk or space before purchasing. The included fans are 120mm; if you prefer 140mm fans, you'll need to buy them separately. The vertical GPU bracket is included, but a riser cable is not. A power supply is not included and must be purchased separately.
