No chance you'll find an X-58 motherboard (triple channel ram) & CPU with onboard graphics - they don't exist. You'll need to add a graphics card if you go that way.
Seems like a Core i7-9xx CPU and X-58 motherboard is a bit much for some who 'she doesn't really need anything much'.
None of the usual prebuilt players (Dell and HP) have i7-9xx CPUs and X-58 motherboards on the Canadian sites.
HP Canada has HP Pavilion Elite HPE-440f Desktop PC
with a quad core i5-760 2.8Ghz CPU, 8GB RAM (dual channel), 1GB HDD, Blu-Ray optical drive, and a Radeon HD 5570 graphics card to power though all those HD videos.
