Optiplex 745 and Optiplex GX270 Upgrade

[HokieHigh]

I have a Dell Optiplex 745 and a Dell Optiplex GX270. What can I use from the Optiplex GX270 to upgrade the Optiplex 745? I can fully take apart the GX270 because I got it for free, I just want to make the 745 as good as it can possibly be for cheap. I know I'm not upgrading a great computer that's why I don't really want to spend money on this. Any help?

In short nothing. The 745 is a ddr2 based core 2 system and is superior to the GX270 with its Pentium 4 and ddr1.
