    Three-speed power control switch

    The IdeaCentre K450 is so powerful we put a 3-speed power control switch on it: turbo red for speed and power, auto blue for normal use, and cool green for quiet, energy-saving operations.

    Graphics Designed for Gaming

    The latest 3D games are smooth as silk with up to NVIDIA® GeForce® GTX660 1.5GB graphics or AMD Radeon™ HD 8670 2GB graphics.

    7.1 Channel Surround Sound

    Whether you're gaming or enjoying a movie, a home theatre audio configuration will help you live the experience to the max.

    Storage & Memory

    With up to 32GB DDR3 memory, you can drive your PC's performance and multi-tasking power to the limit. And with up to 4TB HDD storage you'll have more room than ever for all of your data. Get even more storage capabilities with a portable 500GB SATA Universal Storage Module (USM) hard drive so you can connect to other PCs with a USB 3.0 cable.

    Easy, tool-less expandability

    As powerful as the IdeaCentre K450 is, we've given you the space to soup it up even more. Expandability, easy-to-access hard drive and more ports, slots and connection options than you could ever need. There's room for two optical disc drives, two hard drives, and all of the ports and connectors you'll need. And expansion is a snap with the K450 desktop's innovative tool-free design.

    SuperSpeed USB 3.0

    Enables up to 10 times faster file transfer, allowing for lightning-fast copying of large media files, as well as seamless connections between audio- and video-related peripherals. Backwards-compatible with USB 2.0 devices.

    Integrated DVD Reader/Writer or Blu-ray Disc™ Drive

    Watch movies, listen to music, and burn discs with the K450's integrated DVD reader/writer or Blu-ray Disc™ drive.

    Very quick and very quiet and well designed; easy to service and upgrade
    Really needs WiFi and Bluetooth as an option as well other versions of Windows

    Painful amount of "bloat ware" not needed on the machine as part of the standard Lenovo W8.1 configuration

    Much featured but very much not available is the hot swappable hard disk!

    Power control feature and associated lighting a bit of a gimmick (but it does work); would be better if the lights stayed on rather than "breathed"

    OneKey Recovery works well for the OEM install, but fails (and very slow). The standard windows image saving program is much more resilient and fully reliable and (literally) ten times faster

    The PC is easy to use and to access if you want to clean it or modifiy it.
    The possibility to add/remove an extra HDD is really nice.
    The power supply unit is just enough powerful to supply everything.
    If you want to modifiy somehting (graphic card) you'll have to change it.

    Excellent tracking of order. Easy to set up even though I'm a novice. Works really well, great graphics card.
    Wish I could get Windows Defender to work, but just can't seem to do so.
