Things to Consider

This case only accepts SFX or SFX-L power supplies, so you cannot use a standard ATX PSU. Make sure to check your PSU compatibility before purchasing. The 3.5-inch drive bay count is limited to two, which may not be enough for users with large storage requirements. No fans are included with the case, so you will need to purchase them separately.
