Hi,

Here’s a link that shows the various SSD that are compatible with the desktop. The supplier shown is only to give you an idea of the type of SSD that you can look for. Only suggesting SSD as they will give the PC a performance boost, given the age of the motherboard.

Here is a link that shows how to install an Android OS on a PC that may help.

Here is a link that explains Linux and all the various Linus distributions that are available that you may want to try.

Search online for where to download the OS so that it can be installed on the SSD

As the motherboard is quite old by today’s PC standards, you may want to look at the specifications for the desktop how upgrade some of the components e.g. CPU, memory so as to meet the system requirements of the different OS that you wish to install.

You may also want to check how to make the desktop as a dual boot configuration if you want to have two different OS installed at the same time in the PC i.e. Linux and Android or Linux and Windows etc

Here’s the Upgrading and Servicing Guide that shows how to remove/replace components in the desktop that may also help.

Hopefully a start.
