System information tool
I-Nex is an application that gathers information for hardware components available on your system and displays it using an user interface similar to the popular Windows tool CPU-Z.
I-Nex can display information for the following components: CPU, GPU, Motherboard, Sound, Hard disks, RAM, Network and USB as well as some system info like the hostname, Linux distribution and version, Xorg, GCC, GLX versions and Linux Kernel info.
Besides being able to display hardware information, I-Nex can also generate an advanced report for which you can select what to include and optionally send the report to a service such as Pastebin (and others). It also features an option to take a screenshot of the I-Nex window directly from the application.
The difference between I-Nex and the other hardware information GUI tools available for Linux is that the information is better organized and is displayed faster (than lshw-gtk for instance). Also, the hardware information is presented in a way that's easier to understand than other such tools.
