Heh sorry, slightly offtopic.

I own an old Dell Latitude X300 Portable Notebook which runs very fine with the 10.4.8 Tiger Disk by JaS. The installation takes about 25 minutes.

It uses an Intel Pentium M 738 Processor (1.40 GHz, 2MB L2 Cache, 400MHz FSB) on a Intel 855GM Chipset, 1 GB DDR SDRAM at 226 MHz (PC2100). The Display is a 12.1" XGA TFT LCD with a resolution of 1024 x 768 x 16.7 million colors. The Video Card is an Integrated Intel 855GM graphics chipset.

After some small patching everything is working fine & it runs very solid. The hardware is almost only by Intel, hence very compatible with Mac OS X.

Leopard doesn't seem to be possible, and I like Tiger on that Laptop. :-)
