I believe I've seen some H77 boards with 8 SATA ports. Six Intel (two 6Gbit/sec), and two provided by an add-on chipset.
Edit: AMD FM2 A85X boards also sport eight native 6Gbit/sec SATA ports.
Edit: You won't be able to re-use your RAM.
Rig(s) not listed, because I change computers, like some people change their socks.
