Ebay best offer for the processor (if I did it again I would have paid the extra for the x5687 which is 3.6ghz, ark intel was wrong and said it wasn't compatible, but intel said it was, found that out after I put in an offer. I told the guy that the offer I gave (my second offer of 42 was the last offer he was getting since I planned on getting the x5687, he accepted it, grrr, and I ended up with the x5677 for about $45 shipped to my door, an x5687 runs about 75, would have just been more future proofing I guess. Someday I want to use the second socket, but that will require a beefed up power supply, I am already pushing it with the 130w processor and 175w graphics card.
The gtx970 was on craigslist. They tend to go for around 200 at least around here. Kid I got it from was moving for school, I asked the lowest he would take and he said 140 so I took it.
The ram is just six sticks of 4gb ecc memory I got on ebay. I bought six since I have triple channel and it filled all the slots for one processor while also allowing me to spread the ram over both processors if I ever upgrade. 10600 1333mhz ddr3, I did best offer on that, but the going rate for six sticks of 4 is about 40ish. The ssd I just got at Bestbuy I believe on sale. The cooler for it is the only quiet one they make for a xeon board that will fit in my particular tower without modification (Noctua makes awesome stuff), which I need because my sdr file got changed in the bios update and my case isn't compatible, so the pwm is set at 100% and I just use slow rpm fans with inline resistors to get it quiet. Before doing all the fan stuff it was like a jet just with the cpu, I am adding a rear exhaust because I was having ram erros due to heat, I have a Noctua case fan on the way that has two kinds of inline resistors, so I'll use the slowest one for my annoying 80mm stock case fan and the next slowest for the 120mm exhaust fan. Cost 18 bucks, but that was free money as was the 55 for the cpu cooler since I signed up for a bunch of amazon cards.
My board is a little different than most, so your mileage may vary. Be careful getting a big box store motherboard like a dell or hp, they can tend to be proprietary divas and say you can't do certain things just because. The only thing my s5520sc does that I don't like is the fan issues which have work arounds, however it's a very expensive board, I just got it for free because a friend does IT and the company he did work for upgraded. I think they're still like 400 a crack for a good board, ouch, for that price I would get an SR-2 or just get the newer gen consumer equipment.
