Info I saw says you have a 255W power supply in that. Considering that, and considering that you also need a low profile card, and it'd probably best be a single slot card, yeah of the new cards the 1030 fits your needs.
Of course I have no idea what CPU you have, what games you play, or what resolution you run, so I can't comment on whether the 1030 is 'worth it' or not. It IS an upgrade from an 8400 GS though.
