Win8 Raid5 - 3x3TB - Asus Maximus V gene onboard Raid

Hello all, like the topic says I have just set up my version of a NAS on my Asus Maximus V Gene onboard Raid controller running Win8.

-I started in BIOS chafing the SATA controller to Raid.
-Installed OS on 120Gb SSD
-Hooked up 3x3Tb WD Red's
-Ctrl+I to set up an Intel Raid5 array
-Opened Intel RST driver program and "Initialized" the Raid5 array (Took 32hrs...)
-Opened up Disk Management and.. This is where I'm stuck

The Raid5 array show up as one drive (~5.79Tb) so it was set up properly, it's just that the Array shows up as "Unallocated".

Also it is not visible in My Computer.

I was under the assumption that after the "Initailizing" the Raid5 setup would be complete. What other steps must I make?

Is it as simple as making a "New Volume" on the Unallocated array? If so should it be Simple or Dynamic?

Ps, I selected GPT instead of MBR so I can have this larger then 2Tb in size without having to partition.
