Hi all, I have 2x 5970s up for sale.  Currently part of an underclocked & undervolted rig, so no overheating issues whatsoever in the 3 months that I have owned them.  I bought them new OEM, so the cards still have their 5 year warranty.
Price is 80 BTC each + actual shipping (~2-3 BTC shipped anywhere in the US).  Buy both of the cards for 160 BTC and get free shipping.

Hi, I'm selling 2 Radeon 5970s that I purchased new/OEM 2 months ago and are still in pretty good condition.  Has a 5 year warranty which I'll include the receipt for.
I used them for mining and they run stable at 760 MHash at 810 clock/300 mem.
Card stays pretty cool - I only run the fan at 40-50% and everything in open air cases so there's no overheating.
I'll let these go for 82 BTC each shipped anywhere in the US or best offer.

Yet another reason to use bitcoin.  Perhaps we could help spread the word in that comment thread?

[stock clocks]

Hi all,
I'm currently selling 3 MSI 6950s, reference model, flashed to 6970.  They haven't been used much, maybe a few months of mining at stock clocks in an open air case.
I still have all the boxes/manuals/etc, and they will be included upon request.
These are seriously some of the best mining cards out there - I get 375 MHash with no extra overclocking - bios switch in OC mode.
I've sold a couple things on the board in the past (LED Traffic Lights), but I've been involved in the bitcoin community since 2010.
My current price is 85 BTC each including shipping in the US- payment via bitcoin is strongly preferred.  I'll sell them individually but give priority to offers that want to buy all at once.

[all of them were fully functioning]

Hi all,
I'm currently doing some inventory reduction, and I'm getting rid of some LED Traffic Lights.  They are 12" in diameter, the same as the large ones you see on the street.  

These run off 120V straight from the wall - nothing special is required to make them work.  Simply attach a standard power plug to the light and plug it in.
They are very bright as they can usually be seen for up to 1/2-1 mile at night, and work very well as room decoration, ambient light, etc.  Definitely a great conversation starter.

I currently only have red and green solid lights available (no yellow or arrows).  All of these lights were legally obtained from a Washington State surplus auction.

Although these lights are being sold used, as is, I have tested approximately 10-15 of these at random, and all of them were fully functioning.
There may be scratches on the exterior of some lights, but it does not affect their performance and is virtually non-existent due to the brightness once you turn them on.

Pricing-
1.5 BTC per light
1.3 BTC for Priority Mail Shipping anywhere in the USA (weigh approx 3-4 lbs, dimensions 12"x12"x5")
Shipping discounts may be available for larger orders via FedEx Ground - approx 2-3 BTC can ship 4-5 lights

Pictures below are representative of what you will receive-actual lens/LED arrangement may vary as these lights are made by many different manufacturers.

Hi all,
I'm new to the forums, but I'm a seasoned bitcoin user - started mining over a year ago and kind of forgot about bitcoins until now.
One thing I've gotten into recently has been selling Magic: The Gathering cards, primarily on Amazon and eBay.  It seems that bitcoin is far more mature than it was a year ago, and I'd like to start accepting bitcoin orders on a trial basis - provided there's interest from the community (I know there are other MtG nerds out there!).  I currently have a ton of unopened booster boxes and loose packs spanning Revised - Scars of Mirrodin.  I also have thousands of rare and uncommon singles, as well as bulk lots.  Post here to let me know what kinds of things you're interested in, and perhaps I'll put up some ordering logistics and prices.
