gpuShack R9 270X ETH Mining Equipment 16 MH/s- Refurbished

[SG] I Am Accepting DOGE as Payment for Custom GPU Mining Rigs for Local Pickup in Chicago, IL USA

I have two custom rigs / mining kits IN HAND and I am willing to sell. I will accept Bitcoin or Dogecoin for payment of course, or USD if you prefer I guess =)
Topaz - $850 / 1.7 BTC / 850k DOGE - 2x Sapphire R9 270 GPUs - Motherboard, CPU+fan, 3GB DDR2 RAM - 1x USB Powered PCI-E 1x to 16x Riser - 1x 40GB SATA Hard Drive - 750W PSU - Open air black metal frame - 810 kh/s Scrypt Mining on cgminer 3.7.2
Jet - $950 / 1.9 BTC / 950k DOGE - 2x Sapphire R9 270x GPU - Motherboard, CPU+fan, 8GB DDR3 RAM - 1x USB Powered PCI-E 1x to 16x Riser - 1x 40 GB SATA Hard Drive - 1000W PSU - Open air black metal frame - 880 kh/s Scrypt Mining on cgminer
Sorry but prices in BTC/DOGE are subject to change, I have to pay USD for all of the components here so I have to adjust for the exchange rate. Prices quoted here reflect the current exchange rates and will have to be recalculated if there is significant gain or loss of value on the markets.
Both rigs are mining away at the moment with cgminer 3.7.2, so if you want them they are basically plug-and-play, just need to be configured to point at your pools (which I can show you how to do if you are a newbie). Windows 7 is the 'trial version' so it will ask you for a validation code but it will run just fine without it. I am also willing to build and deliver fully working CUSTOM MINING RIGS at various hashing powers - 800, 900, 1200, 1500, and 2200 - for around $1.25 per kh/s (with payment up front).
Professionally I am a career educator, so I am very patient and willing to sit down with you if you are unfamiliar with crypto and explain how everything works. I will make sure that the miner I sell is configured right and ready-to-hash, and I will explain to you how to use it and how to keep it running right. I have mined scrypt coins on several different types of cards using both Linux and Windows OS, I have mined BTC using ASIC hardware, I have managed exchange accounts, qt-clients, and a futures account on ICBIT. So basically I have some knowledge and expertise I am willing to share with anyone who is interested and willing to invest some money with me for hardware.
I think that GPU rigs are still a very good investment in crypto for two reasons. At the moment the scrypt coin economy is pretty stable. 1,000 kh/s will get you the equivalent of 0.010 - 0.015 BTC/day depending on which scrypt coin you choose. There are several coins that give at least this good of a return, which is great on its own. But then add the fact that GPUs can be resold for a very good portion of the original value, and that a mining rig can be re-purposed as a workstation or gaming rig. Personally I think I can offer a really good value, and if my apartment were rated to deliver more electricity without overloading my circuits, I would be building and mining off of more cards myself.
I am also willing to buy/sell limited amounts of cryptocurrency in person - up to $1,000 USD. I have well established accounts on major exchanges so if you are looking to buy or sell without all that hassle, I can help you out.
