Desktops & All-In-Ones

[Aspire_Z3771]

Hi.

I recently purchased a Z3771 All in One. I'm happy with virtually all aspects of the machine except the graphics capability. I've read another post on the board where a user says he's installed a graphics card into the machine.

I have several questions regarding this:

What type(s) of card does the Z3771 take?

Are the cards easy to fit - could a beginner fit one or would I need to seek professional help?

If no card(s) are available, are there alternatives - ie USB external graphics cards etc?

Thanks in advance.
