Hi all,
From a functionality perspective a B-Grade motherboard should be, and you should expect it to be, 100% functional, delivered usually in a plain box with little if anything else.
Unfortunately, the motherboard manaufacturers do not generally ship B-Grade motherboards, which can be are either new or reconditioned boards, with any other items i.e. instructions, connectors, backplates etc.
By the very nature of our business we sell 100's of motherboards a day, a number of which will be B-Grade, what we cannot easily do is clearly define the exact variations between different B-Grades of the same product - thus I refer to Meridian's comment - "Usual rule: hope for the best but expect the worst" - assume you will get a Mobo in a brown box - anything more is a bonus....especially for £0.12
Cheers
