Well according to this: http://www.limewire.com/english/cont...oadfree2.shtml you should have Minimum Requirements:

* 64 MB RAM
* Any of these operating systems:
Windows XP, 2000, 98, NT, 95,
Mac OSX, Mac Classic 8.1 or later,
Linux, Unix such as Solaris
* An active Internet connection

But I would tend to recommend more ram (256 MB +) & sufficient hard disk drive space ... a few gigs or more HDD space.
