what are minimal hardware & system requirements for Eclipse & LWJGL :?:
Eclipse is a fairly hefty IDE; don't reckon on being able to use it well with under 256MB of RAM and 700MHz processor.
LWJGL runs blazing fast on any system with hardware OpenGL drivers. In practice this means TNT class cards and above are just fine. Mostly it's problems with rubbish drivers that you need to be concerned about - S3 and Matrox and ATI spring to mind as causing a world of trouble with broken drivers.
