This is a custom computer with an HP motherboards and case. The case is repurposed with a slightly newer motherboard. Both the case and motherboard are made by HP. The motherboard used is from the HP 500B business series computer. It is intended to be budget friendly while providing a modern operating system. This works well for everyday things, data processing, school work, paying bills online, home office and more. This and other computers that I have can be customized for your specific needs.
