    ThinkCentre M78 Tower DesktopFeatures


    Tower desktops provide the ultimate performance with full-featured scalability, yet weigh about 27.6 lbs.

    Platform Stability

    The M78 desktop features 15-month platform stability with no planned hardware changes that affect the preloaded software image.  Image stability for long-term deployments helps to reduce transition, qualification, and testing costs to ensure savings for your business.

    Multiple Monitor Display

    Maximize productivity with triple independent display support. The expanded work area and easier navigation between applications helps reduce errors and improve productivity as you extend your desktop across four monitors. Requires optional discrete graphics card.

    Solid Security & Manageability

    M78 desktops include some of the best security tools available in the industry, including USB ports disablement to help prevent data theft and network security risks against unauthorized use of storage devices. Trusted Platform Module (TPM) encrypts data and key information like passwords and digital certificates, further securing applications, electronic transactions, and online communication. Desktop/mobile Architecture for System Hardware (DASH) 1.1. provides a host of capabilities to tighten system security and to address growing IT requirements through remote manageability.

    RapidBoot Performance

    Lenovo's exclusive RapidBoot HDD Accelerator dramatically reduces startup time by copying and compressing Windows boot files and reloading them to RAM.

    Tool-Less Expandability

    Upgrades are a cinch for IT staff, with convenient tool-free access to hardware. Especially beneficial when multiplied by multiple desktops.

    Advanced Thermal Design

    Our Intelligent Cooling Engine (ICE) 2 is designed to provide a balance between thermals and acoustics resulting in long desktop life. With two optimized settings, you choose the performance mode that best suits your work environment, prioritizing temperature or sound. Plus, ICE 2 allows for working in hotter temperatures and enables system monitoring with thermal alerts that preempt overheating possibilities.

    Green Leadership

    Cisco® EnergyWise certification enables enterprise-level power monitoring and Lenovo Desktop Power Manager puts you in control of saving energy and keeping costs down. Plus, with ratings like ENERGY STAR 5.2, EPEAT® Gold, and ULE Gold, you can feel good about helping the planet and your bottom line.
