The CiT Prism is a Midi Tower gaming case with a combination of a metal mesh and semi transparent front panel and with a plastic front door also included makes this different to other CiT models.

The two 120mm RGB front fans give the Prism a unique style, whilst keeping the system cool. With the ability to install up to 3 x 120mm fans (2 included at the front and 1 x 120mm fan at the back) and a water cooling kit with a 240mm radiator (which can be positioned at the front), the CiT Prism should keep even the most demanding gaming systems cool.

The I/O Ports are conveniently located at the top of the case, giving the user easier access. The all black coloured interior and exterior gives the case an outstanding design.

With safety in mind, the edges of the Prism are all rolled to minimise any injuries whilst building the system. The Prism supports the following motherboard types: ATX, Micro ATX and Mini iTX.

Please note the main image shown is for visual purposes only. The fan included is RGB (solid RGB colours only) and not an ARGB spectrum fan (where the colours merge).

Main Features

  • Front Panel - The front panel made from metal mesh and a semi transparent front panel, along with the underlying 2 RGB fans, give the Prism a unique look.
  • I/O Ports - 2 x USB 2.0, 1 x USB 3.0 and HD Audio located at the top of the case.
  • Side Window - Clear side window, allowing the user to show off their internal components.
  • Large GPU Support - A maximum length of 415mm for graphics card.
  • Large Cooler Support - A maximum height of 163mm for CPU coolers.
  • Internal Cable Management - A maximum depth of 20mm, allowing for the cables to be routed to keep the components cooler and looking less cluttered.
  • Up to 3 x 120mm Fans - At the front 2 x RGB fans included and 1 x 120mm fan can be fitted at the rear of the case.
  • Water Cooling Support - A 240mm water cooling raditator can be fitted at the front of the case.

Very good quality Metal is hard and steady Very good looking

Great value for money! I bought this to build a friend's gaming PC in; one of increasingly few cases with a 5.25" bay. The cable management is very good and I love that the PSU and HDD bays are hidden below the eye-catching stuff. Some of the connectors are bit poorly moulded but seem operable. I don't think the feet are height-adjustable; that would add value and cost very little.

Case is very bendy and the flitted fans have a very low cmf of air flow but other then that the case is great for a beginner to leant the basics of pc building


October 2019

A mesh front case with RGB fans and space for those who want a DVD drive, and the fashionable PSU basement shroud. One of a limited number of reasonably attractive cases with provision for an optical drive. The bad points: First, the elephant in the room, the picture is misleading in interpretation, as while the fans are RGB adjustable, they are not ARGB rainbow. On the plus side, they do provide a decent amount of illumination inside the case, as well as showing through the mesh. There is a gap which allows the fans to recycle from the inside instead of drawing from the front, so it really needs a rear fan fitted to ensure it draws air through. HDD mounts in the basement are awkward, not tool-less, and can really only be reached to get one screw in with the PSU removed (to get a screw in the other side would require removing the front panel and the lower fan). Do I regret choosing this... no, it fits the bill quite well if you insist on having a DVD, and while there are better options (such as the CIT G-force which puts the optical drive behind a door - good when closed but ugly when open), they are more expensive. This case also looks ok with the mesh plate which fills the optical drive in place (and with care, you can unclip the plate without destroying it, so it can be refitted if required), but there is really no point in this case if you don't need that bay.
