Receiving the Thunder n6650EX we had just the motherboard itself in a very well protected cardboard box. However, the retail motherboard package for the Tyan S4992 should include a few SATA power and data cables, SAS cables, S4992 user's manual, a quick reference guide, driver CD, and the I/O shield. With this motherboard having four CPU sockets and being sized for an MEB enclosure, the Tyan Thunder n6650EX is quite large at 33 x 41 cm.
