Seriously, this isn't hard. You have ALL the info you will need in this forum FOR FREE. MANY people here have done everything under the sun to try to squeeze more out...some pretty smart people.
You should concentrate on getting more product and turning it over....unless you have people bringing it to you by the car load.
1) motherboards - how much to scrap? I see people scrapping connectors, valuable capacitors, 'crystals' and IC chips and selling those in bulk. Should I scrap as much valuable stuff from it as I can?
I do pop off tantalum, the cpu, pull ram and remove heatsink (no reason to ship AL or CU). Otherwise, into the pile it goes.
2) does anyone have a full list of most common golden plated connectors? Some are easy to see, some aren't. Like IDE.
gold connectors are not worth much right now...I mean for every POUND of them you might clear another .20. Take alot of pounds to hit my per hourly goal.
3) should I throw all cables in one bulk, or separate them - like ribbon wire?
Ask your buyer...communication cable (networking) can be worth more and most ribbon cables are really just steel
4) assuming that answer to n.1 is no... can I still sell the scrapped motherboards, or should I Just trash them?
This is where reading this forum would have answered this...umm...NO NO NO, do not throw them away...they can be worth $1.50 to over $3 a pound
5) with small cards that have golden fingers. Should I sell them as they are, or strip the finger and IC chips?
Sell as finger boards (last ones I sent were $3 pound or so).
AGAIN, to see how much stuff is selling for, jump on buyers section and look. Ewasted has a HUGE price list as does many others. If you aren't educated on what things are, then DO THAT before you do anything else. KNOW, what components are in a computer at least. The rest will be an education on the job so to speak. Some boards (when you send a pic will go for more than you though...some not so much). Eventually you will have a pretty good education in about 5-6 months if starting from scratch. BUT READ...the "gold" is right here in this board...real world experience and knowledge...all for FREE.
