Dimension 9150/XPS 400 – Windows 7 64 Bit

This system is a 2005 system and with some push can run Windows 7 64 Bit. It is not Windows 10 64 Bit Capable due to elevated Processor Requirements. Note the XPS 400 and the Dimension 9150 are the same hardware. It is not advised to spend any money upgrading this system, as it is cheaper to purchase a more capable Second Hand Business Desktop
