Picked mine up yesterday, can confirm that the Rails came with it and the Raid card (FRU 03x3744 [LSI MegaRAID SAS 9260-8i card]) was indeed included. Also came with the FRU03t8872 TPM module.
The second PCI-E Riser card was also installed but CPU#2 is need to use it, a heat sink for CPU2 was not included. Powered it on and performed the BIOS and BMC updates last night from the web console, overall the system exceeded my expectations on how quiet it would be when idle. Can post pictures later is anyone wants
