The get-wmiobject command is a very userful tool for Windows Admins to manage the remote inventories, for example, you can easily get the bios version, Serial Number and other bios info by using the following command:

get-wmiobject win32_bios -computername Test-PC1

you can simply get other info as well, here are some parametres I used a lot:

win32_computersystem, win32_processor, win32_logicaldisk, win32_diskdrive, win32_physicalmemory
