Did you have it made for you or does it come from one of the major manufacturers?
I had it built at a local PC shop/repairers. It was based on one of their "standard" builds but modified by having a less fancy case, 2 x 1TB HDD's rather than 1 x 2TB, 2 DVD-RW drives and a slightly less expensive video card; NVidea GTS 250 rather than ATI and I have Windows 7 - 64 bit.
