My NUC is equipted with a 60GB SSD disk, 1 TB 2½ SATA3 disk, 8 GB Ram, Wireless module.
Im dual booting Linux Mint 17 and Windows 8.1 both with UEFI boot and GRUB. (GRUB boots first, then Windows boot mananger). I installed Windows first, on a 200GB partion on the 1 TB Drive, and then I installed Mint 17 on the 60 GB SSD disk (/root) and 500 GB (/home).
Im actually only using Mint 17, bacause I have install VirtualBox on top of Mint 17, and then a new Windows 8.1 in VirtualBox.
The NUC can smoothly run my Mint 17, a Virtual Windows 8.1 and a virtual Linux Mint Debian and a virtual Debian. And everything still runs smoothly. VurtualBox installed on the SSD disk, but the Virtual machines is running from the 1 TB SATA 3 disk.
