The memory kit isn't really that special, just 2x 1GB of DDR2 800MHz memory with high 5-5-5-15 timings.
The special thing is the package in which the memory arrives. Mostly memory ships in a plastic blister box but Mushkin gone out of their way by shipping the memory in a wooden box. Kinda overkill IMO, I'd rather see some fancy heatspreaders on the memory instead
