@Phipli The LB is essentially a 9500 with a PCI bridge providing four of the six PCI slots instead of doing it properly. Besides that and the second CPU socket (only usable with official SuperMac P-series CPUs, which are stupidly rare) there are only a handful of minor differences. PCI cards with bridge chips do not work in the lower slots, which I am currently trying to hack my way around.
