A HPĀ® desktop computer is a practical choice with a wide array of features that vary in categories such as memory, storage, video processing capabilities and support for accessories. It allows you to tackle tasks ranging from everyday computing to business, gaming, multimedia and hosting a server.

Get the Setup for Your Needs

AĀ HP desktop computer with 4 GB of RAM is enough for most basic users, but choosing a model with 8 GB gives you some wiggle room for slightly more demanding applications. An IntelĀ® Celeronā„¢-powered device like theĀ J5N50UT Chromebox Intel 2955U Mini PC works for basic users on a budget. If you plan on doing some light gaming or watching movies, a Coreā„¢ i3 or i5 processor makes sure your ProDeskā„¢ 400 G5 HP desktop computer will handle such tasks easily. For serious gamers, choose a desktop from HP's Omenā„¢ line like the 25L. If you value a smaller footprint and easier setup, an all-in-one computerĀ works, especially for families. This configuration is easy for children to use, as it has a touchscreen and large monitor.

Boost Your Business Productivity

AĀ Z2 G4 Tower HP workstation desktopĀ is suited for serious commercial use, including graphic design, virtual reality and computer aided design (CAD) work. It comes with the latest and most powerful multi-core Intel processor to handle multitasking and power-intensive applications. With some of the most powerful video cards on the market, aĀ HP workstation desktop allows you to precisely and accurately design and see what you're building. For server and cloud hosting, a server workstation system like the ProLiant ML30 Gen10 gets the job done, thanks to its Intel Xeonā„¢ CPU. The Xeon has the ability to keep running for many hours on end under an intense workload, which makes it a proper choice for HP business desktops. For smaller operations, such as small businesses and schools, you can choose a smaller form factor to save space. A HP mini PC like the EliteDesk 800 G4 is thin and compact, yet it still packs plenty of power.

Unlock Your System's Potential With Accessories

If you plan on enjoying games and other multimedia, add a headset to your desktop from either wired or wireless options. Get the most out of a gaming desktop by connecting it to a gaming keyboard, mouse, joystick or other controller. If your HP desktop computer does not have an internal optical drive, add an external one for the easy watching of movies and other content. An additional hard drive or solid state drive is a nice way of taking advantage of an extra drive bay in the desktop. In addition, other computer accessories such as a webcam, USB hub or power dock add more functionality to your HP business desktop. You can also add more RAM or an additional discreet graphics card to boost your system's performance.
