I was almost a purveyor of "fine custom builds" for the sig 2600K. A friend wanted the whole enchilada, with the OC profiles, custom ducts, the cooler, fans PSU and case. I looked at the price of parts on EBay and Amazon, took the least price and dropped $40 off the CPU. Knocked the used graphics card down $50 = 20% of a used price $250. 850 W Seasonic free, all but one fan free, fair-used price for the cooler, half price for the case plus $20 for the custom caster wheels. Then he flip-flopped, but before he expressed interest, I'd already planned to use it for replacement of my Moms's system when I might get around to it or Moms' failed. I could rebuild her system any time, and he was eager to get the 2600K system. His wife complained he had too many computers and she was tired of all his junk.
I was asking $540; he would pay shipping. I would provide foam insulation in cardboard and other safety packaging.
Today, me Moms system went south -- a Gigabyte GA-73VM-S2 mATX with Wolfdale E6700 and 4GB DDR2. Some of the symptoms could have suggested the graphics card for which I have a replacement; other symptoms made the motherboard suspect. But only the Power LED and the fans would come on at the end of my attempts, and the drive light wouldn't flash.
So I'll just throw the Wolfie and RAM in a padded envelope to my friend in Virginia, and the rest goes to the recycler. The Seasonic 650 was about five or six years old, and I haven't room to store it or time to test it. I still have another computer to replace, and the replacement is sitting in the corner awaiting the OS installation.
The best part: I can retrieve the essential data files from the WHS'11 box and simply add them to my cleaned, purged and revitalized Win 7 on the Sandy. I think Win 10 is too much for Moms, and she doesn't want to do it. But it's all there in dual boot, configured to default to Win 7.
It's all just as well.
