This from the PIONEER website
General System Requirements:
Windows 2000/XP*, 800MHz Pentium III or faster, 256MB RAM,
20GB hard disk, 24-bit colour graphics display (1024 x 768 resolution)
For real time editing a Pentium 4, 1.8GHz or higher system with Windows XP is recommended,
512MB RAM, 40GB hard disk, 24-bit colour graphics display (1024x768 resolution).
So going by that I would say no it is not powerful enough.
edit: I have a Lite-On ldw-411S that I use in a P3 550E with 40gig HD and 512MB ram and that works ok, it is very slow at ripping but has no problems burning @ 4x, so if you get a 108 and have problems at high speed with buffer under run and the like try burning at a lower speed it may work ok.
