The X-Seed 4000 was a concept for a megatall skyscraper. [1] Its proposed 4-kilometre (2.5mi) height, 6-kilometre-wide (3.7mi) sea-base, and 800-floor capacity could accommodate 500,000-1,000,000 inhabitants. This structure would have been composed of over 3,000,000 tons of steel. With the drive cage in its starting position in the middle of the case, however, adding a power supply is nearly impossible. For this build, I used SilverStone's fully modular ST75F-PT power supply, and ran into trouble almost immediately. Without moving the cage, I could fit the power supply without any cables attached to it into position, but the space between the PSU and cage was too cramped for me to then add cables to the PSU.

Show off your components and RGB lighting, with dedicated front ventilation channels for ample airflow. The whole tempered glass made the case look good. Corsair iCUE H115i AIO is installed in top of the case. Since this build is installed with low height memory modules the AIO is having a very close clearance with top of memory modules. Pros The X-Seed 4000 was projected to be twice the height of the Shimizu Mega-City Pyramid at 2,004 metres (6,575ft). POWERFUL DIRECTED AIRFLOW- Equipped with three CORSAIR 120mm fans featuring AirGuide technology with anti-vortex vanes to concentrate airflow and enhance cooling. The case comes cradled in two expanded polyethylene foam supports, which is surrounded by a bag to help keep it clean and protected. For accessories we have a user manual that was sitting in the bottom of the box, and the hardware and cable management accessories that are stored in one of the 3.5in drive bays.RGB LIGHTING OUT OF THE BOX- Fully control and synchronize the RGB lighting for up to six fans with the included iCUE Lighting Node CORE and CORSAIR iCUE software. Our 4000 Series and the most recently launched 5000 Series cases have arrived! Both lineups signal a return to classic CORSAIR styling with a focus on improving the build experience, flexibility, and performance over our previous lineup of cases. CORSAIR iCUE 4000X RGB Georges Binder, managing director of Buildings & Data, a firm which compiles data banks on buildings worldwide, said the X-Seed 4000 "is never meant to be built . . . The purpose of the plan was to earn some recognition for the firm, and it worked." [4]

CORSAIR RAPIDROUTE CABLE MANAGEMENT- Route your major cables through a single channel, with a roomy 25mmTEMPERED GLASS SIDE AND FRONT PANELS - Show off your components and RGB lighting, with dedicated front ventilation channels for ample airflow. The iCUE 4000X RGB has removable storage consisting of two 2.5in drive trays, and a 3.5in drive bay with trays for two 3.5in or 2.5in drives. All six fan mounting locations can take 120mm-width radiators, while the front and top fan bays can take up to two 140mm-width fans and up to 280mm radiators. Using a 280mm radiator in the top will limit your RAM choices to Corsair Vengeance LPX or similar profiles. Inside the main compartment of the case is the motherboard mounting tray and a raised lip, which isn't for cables as you might think (more on this later). There are cutouts all along the motherboard tray to let cables pass through where needed, which helps make for a tidy finished build. Fully control and synchronize the RGB lighting for up to six fans with the included iCUE Lighting Node CORE and CORSAIR iCUE software.
