You may or may not require a crossover cable. According to fordem, gigabit devices do not require them.

Wiggs,
I believe what I said was
most gigabit devices, and since I have personally connected my DNS-323 directly with a straight through cable, I can state that the DNS-323 does not require a crossover cable. It will require static ip addressing or you can enable the DNS-323's DHCP server.
Personally, I see no advantage to connecting a NAS to a single system, especially one like the DNS-323 - if what you're looking for is an external drive, go with USB or firewire, it'll probably be less expensive and it'll definitely be faster, and yes dual bay, BYOD, RAID USB enclosures do exist.
