The designs available allow for premium enthusiast level hardware to be installed without compromising on cooling so that you can build a tiny powerhouse system that is portable yet packs a massive punch..All Lazer3D products are designed & manufactured in the UK as standard, meaning that not only is quality guaranteed, but customisation is available on a relatively short lead-time. If you can\'t see what you are looking for, please get in touch and we\'ll see what we can do!The Lazer3D LZ7 XL-Top Vent panel is an alternative top panel for the LZ7 providing increased ventilation and cooling compatibility options such as mounting an extra case fan or 120mm AIO water cooler. This panel is intended for use in combination with DC-DC power supply configurations. Opting for DC-DC instead of SFX power supplies opens up the full height of the case, giving you extra cooling options such as up to 130mm tall CPU coolers. The drawback of DC-DC power supplies is they require an external power brick (AC-DC adapter), have limited wattage and tend to be more expensive.Depending on your overall system configuration, the Top XL-Vent panel is compatible with 1x 120mm AIO watercooler, or 1x 120mm/140mm fan, or up to 2x 92mm fans, or up to 4x 80mm slim fans*.*Compatibility of fans and AIO cooler is highly dependent on your overall system configuration, which includes:-Power Supply type (SFX / DC-DC / AC-DC Adapter / PicoPSU / etc)- Power supply position (mounted to Rear Panel or Front Storage Panel)- CPU Cooler height (total clearance above CPU is 130mm)- Graphics Card Height/Width- The options are limitless, so please approach Top XL-Vent Panel fan compatibility with caution.Specification- Type: Lazer3D LZ7 Top XL-Vent Panel- Material: Acrylic- Colour: Midnight Black
