1/6, low peripheral 2/3/4/5/7, high peripheral
There are a few things on the "junk" side of 1 that aren't junk, granted I can't see the pins in the ports so there may be less than I'm thinking. I personally try not to remove components or cut boards up, if you don't know what you're doing and routinely chop boards up Boardsort may downgrade material. That's not to say it can't be done; I just don't do it. Removing components can be a little more forgiving especially if a board is already low or midgrade. Anywho back to 1, if you really wanted to you could remove the aluminum and ferrous materials on that side and probably be at high peripheral.
As far as set things being required to hit specific grades, it depends on the grade. CD/DVD board needs specific chips to be present otherwise they don't meet the grade. High grade hdd boards is almost any hdd board that doesn't use sata (or as I recently discovered, USB/firewire/similar). Motherboards have specific sockets to sort by. Things like low grade, midgrade, peripheral, Telco aren't strictly one way or another on what components will be on the board. Obviously the value from the first to the last in that abbreviated list go from lowest $/lb to highest $/lb and having more high value components with less lower value ones will help get you closer to a Telco grade than midgrade. That being said there are certain boards that are mass produced at such a scale that you can say 90% of card readers from a desktop are low peripheral or 85% of desktop pci expansion slots are backplane (percentages here are representative not actual) and as you get used to seeing certain boards and knowing their grades you can guage where other boards fall or notice when a "typical" board looks to have more going for it in terms of value.
