Once you have gathered information about your computer's hardware, check that your hardware will let you do the type of installation that you want to do. Depending on your needs, you might manage with less than some of the recommended hardware listed in the table below. However, most users risk being frustrated if they ignore these suggestions. A Pentium 4, 1GHz system is the minimum recommended for a desktop system. Any OldWorld or NewWorld PowerPC can serve well as a desktop system. Install Type RAM (minimal) RAM (recommended) Hard Drive No desktop 64 megabytes 256 megabytes 1 gigabyte With Desktop 128 megabytes 512 megabytes 5 gigabytes The actual minimum memory requirements are a lot less than the numbers listed in this table. Depending on the architecture, it is possible to install &debian; with as little as 20MB (for s390) to 60MB (for amd64). The same goes for the disk space requirements, especially if you pick and choose which applications to install; see for additional information on disk space requirements. It is possible to run a graphical desktop environment on older or low-end systems, but in that case it is recommended to install a window manager that is less resource-hungry than those of the GNOME or KDE desktop environments; alternatives include xfce4, icewm and wmaker, but there are others to choose from. It is practically impossible to give general memory or disk space requirements for server installations as those very much depend on what the server is to be used for. Remember that these sizes don't include all the other materials which are usually to be found, such as user files, mail, and data. It is always best to be generous when considering the space for your own files and data. Disk space required for the smooth operation of the &debian-gnu; system itself is taken into account in these recommended system requirements. Notably, the /var partition contains a lot of state information specific to &debian; in addition to its regular contents, like logfiles. The dpkg files (with information on all installed packages) can easily consume 40MB. Also, apt-get puts downloaded packages here before they are installed. You should usually allocate at least 200MB for /var, and a lot more if you install a graphical desktop environment.
