We were moving offices, so people were throwing a lot of parts into e-waste. The parts were "older" and certainly all in "used" condition, but in working order. I took advantage of the plummeting GPU prices and scored a 3070 below MSRP and finished off the build. My biggest score in this build was the memory. The whole kit of four sticks was discarded and the DIMM in slot one sometimes doesn't light up. So maybe it was an RMA or something. But it seems to be a firmware problem because if I just run iCUE and go into the DRAM tab, and it comes right on!
I'll add more of the parts descriptions once I've got things more situated.
