First, find a motherboard with 6 SATA on it. It should not be difficult
to find a board like that.
Second requirement, is to find a motherboard with several PCI Express x1
sockets.
Then, purchase SIL3132 cards, which have the hardware to control two
SATA ports. (The card you purchase should have two physical ports,
and you don't want a card which offers two external and two internal,
as with the SIL3132, they cannot all be used at the same time.)
This one is $37 and offers two internal ports.

An alternative expansion scheme, is to use a single SIL3132
card, and use two of these port expansion boxes. These cost $100
each, and turn one port into five. By using a $37 SIL3132 card,
and two $100 expansion boxes, you can run 10 disks. Plus the 6 on
the motherboard itself.

Actually, I do see a board that has 8 SATA ports and three
PCI Express x1 slots. 6 SATA are on the Southbridge (ICH9R).
2 SATA are connected to what looks like a JMB363 or equivalent
(Gigabyte likes to hide the identity of the chip, for no good
reason). You can slap in at least one more SIL3132 card
if you want.

I don't know if multiple SIL3132 cards "play nice" in the
same computer, so you have a bit more research to do.
In terms of volume size, there is also a limit at around
2.2TB on some versions of Windows. That is another thing
to take into account, when setting up the box. If all the
disks are independent of one another (each with own drive
letter), then that shouldn't be a problem.
