The Core 3000 USB 3.0 has plenty of cooling options with space to install up to 7 fans of various sizes. The front panel is easily removable and pre-fitted with fan filters to ensure a dust free interior. The sleek black interior is matched and contrasted with white expansion slots and HDD trays. Similar to the Define Series, all the HDD trays are fitted with anti-vibration silicon grommets. The upper HDD cage is removable and rotatable, which allows for installation of even the longest graphic cards.
