It depends on what hardware specs you have. I have sucessfully installed it on a few Compaq's with no problems. The lowest compaq specs I've used so far was:
Compaq 5000US -
Duron 750mhz
256mb RAM
20 Gig HD
CD-ROM
intergrated 4mb nVidia graphics (I think)
Installed Debian, SuSe 10.1, and Ubuntu on it.
Have fun!
