Please make offers in this thread, you can lowball if you want but I will probably just not respond. Bought all of these parts new in January 2014, and now am parting out a mining rig because I will be moving soon and no longer have room to run a four-card rig.

1x Motherboard ASRock MB970EX4 http://www.newegg.com/Product/Product.aspx?Item=N82E16813157262 - $70

1x CPU AMD Sempron 145 (with heatsink and fan) No link needed for this, they are like <$40 new and I would be surprised if someone bought this used - $20

1x 8GB Crucial Ballistix Sport (Low-Profile) RAM http://www.newegg.com/Product/Product.aspx?Item=N82E16820148540 - $60

1x Corsair CX750 PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817139040 - Offer

1x Thermaltake SMART 850W PSU http://www.newegg.com/Product/Product.aspx?Item=N82E16817153158 - Offer

(The power supplies I way overpaid for at Best Buy. The story goes: I had ordered an EVGA 1300W PSU and TigerDirect confirmed my order, didn't pay attention to if I had actually been billed, all my other parts arrived except for PSU, checked and saw it hadn't even been shipped. Instead of waiting an extra 1-2 weeks on a PSU I just canceled that order and ran to Best Buy and bought the best PSUs in stock, and linked them together with an Add2PSU-style cable minus the relay switch).

4x [16x-> 1x] PCIe riser cables (Originally paid $20 each). Not expecting these to sell since it seems like USB risers are the rage now

Also selling 2x Asus DC2T R9 280x GPU, already sold the other two. - $400/card


Shipping will come from the midwest USA.

[$1700.00]

Selling 4x ASUS R9 280x cards because I am moving soon and will no longer have the space to run 4-card rigs. These cards were received in early January 2014, purchased from Newegg, so still a very long time remaining on the 36-month ASUS warranty. Willing to ship via any carrier and option you like (you pay shipping). Will be shipping from the midwest USA as soon as payment is confirmed. Placing them for sale here for a few days, and if there is no interest will just put them up on eBay.

If you are curious about hashrate, some forum posts claim these cards can push 805 kh/s, although I always ran them stable at 737 kh/s and 71C because I did not want insane power bills.

These cards sell brand new on Newegg currently for $529.99 + shipping, or $490/card on eBay (http://www.ebay.com/itm/Two-2-ASUS-R9-280X-3GB-R9280X-DC2T-3GD5-Radeon-CrossFireX-Video-Cards-WARRANTY-/171249256389?pt=PCC_Video_TV_Cards&hash=item27df4047c5). Cards have consecutive serial numbers if that matters to anyone.

I am willing to sell for $470/card individually, or all four for $1700.00 (~3.3BTC) ($425.00/card).

Would prefer to use Escrow (required for Paypal, optional for Chase Quickpay or BTC).

Please leave feedback about trades with me here, thank you!

Edit: Nevermind

Please feel free to PM or post here, hoping to buy new but willing to risk buying gently used.

Paying in BTC or pretty much any altcoin.

Open to using escrow.

Thank you!

I have the chance to buy quite a few 7770 Ghz Edition, but I am not sure what type of pricing to look for. The cards are used and to the best of my knowledge have never been used for mining before.

Does anyone know roughly how much I should realistically pay for each card?
