I'm looking to pick up a computer off craigs list to play with. I found 2 different machines and am not sure which would be the smoothest install.

Machine 1:
MPC Clientpro
- Pentium IV 1.5 Ghz Processor
- 256 MB RAM non-ECC RDRAM
- 20 GB IDE HDD

Machine 2:
Dell Optiplex GX240
- Pentium IV 1.5 Ghz
- 256 MB PC133 non-ECC RAM
- 20 GB IDE HDD

I have pulled down iDeneb 10.5.5 to install once I get the machine. I think I have an extra hard drive at home to beef that up and I'll get some more RAM as well.

I appreciate any advice on which machine would be a better buy.

Thanks
