ASRock has never been a company to package more accessories with their motherboards than the average enthusiast would ever use, and they didn't start now. The P43R1600Twins-WiFi just includes four Serial ATA data cables, one 4-pin molex to SATA power adapter, 802.11g WiFi module with expansion slot bracket, 802.11g antenna, I/O panel, one ribbon FDD cable, one ribbon IDE cable, Windows driver CD, and a user's manual for the WiFi module and motherboard. The P45R2000-WiFi included the same accessories but with six SATA cables instead of four. The product packaging for these two motherboards are similar and the box has gone with the newer ASRock black theme than the rather generic cyan design we've been accustomed to in the past.
