You can create a Windows 2003 VPS the same way you create a Windows 2008 VPS. The fee we charged for a Windows 2003 VPS are the same as the fees we charged for a Windows 2008 VPS.
Billing
Our system will treat Windows 2003 and Windows 2008 the same. That is why your invoices will state 'Windows 2008' despite the fact that you're running a Windows 2003 VPS.
