Sometimes old tools are the best, or at least adequate. In this case, we're talking about HardInfo - a tool that hasn't been updated in about 7 years, but still does a great job.
Once you have installed inxi then terminal codes [note space between inxi and -]
inxi -F will give a general overview
inxi -Fnx will give a few more details,
sudo inxi -Fnmx will give more details of network and memory
If you are asked to run any inxi command to be pasted back to the forum always add a z to the end, this filters out some sensitive information [inxi -Fnxz]
