The question I am about to ask hopefully I will be able to answer myself in the near future. I have a Gateway (Windows 9

that I have not used in years and I was wondering if I could use this to study on to prepare for CompTIA A+ Essentials? I know that the chips and so forth in the Mother Board are probably obsolete, but could I train on this by upgrading to maybe Windows XP? I guess I would probably have to replace everything inside, is this correct? The model# of the Gateway is
MICRO ATX FMN ESSENTIAL 400C. Would appreciate any assistance.
