In the worlds of Avalon "Avalon4.1 – 1.3T consists of 40 A3222 chips, with improved heat dissipation, which can be controlled by Raspberry Pi or TP-Link TL-WR703N." Below is list of items you need to buy in addition to miner. Ofcourse some of you might have these in your parts pile and already be a step ahead.
- Standard power supply with 4 PCI-E 6 Pin adapters (up to 1000 watts depending on setting, also at underclocked you only need 2 PCI-e cables(One on each blade).)
- Raspberry Pi or TP-Link TL-WR703N
- Network cable
1) UnpackingThe miner had a decent sized trip from from EHash to my door in middle of US. It was shipped via DHL and made it to my door in 5 day's. First thing you will notice is a box. Mine made the journey without any problems as you can see below. And in the second picture you can see it was well protected with styrofoam around the miner.

3) InstallThe install is not hard at all with the guides posted on EHash:
http://downloads.canaan-creative.com/people/lili/doc/controller/First you will need to flash either a Raspberry Pi or the TPlink. I personally chose raspberry pi as I had one laying around. The main guides I used were:
1) The Raspberry PI SD flash guide:

http://downloads.canaan-creative.com/people/lili/doc/controller/Raspberrysetting.docAs far as a general guide you will reflash your Raspberry PI with a pre-made image of a custom DDWRT install for the Avalon hardware. After flashing you need to connect to the Raspberry PI. In my case I had to log in and change the IP address to 192.168.1.X IP. I would say it's a 15 minute install if you don't have any trouble. I did run into some trouble and Canaan-Creative does have a great support team and they helped me though it.
4) RunningFor these results I am running at a under clock

- The air temperature before and after being sent through exhaust:
- Sound: This miner is crazy quiet with a underclock and fan at default of 20 percent. I went to take a YouTube video to show off how quiet it is. I had to turn off my overhead fan, my projector, and close my window. And still could barley hear it. Link to video: https://www.youtube.com/watch?v=d7UTdo_4AaQ
5) ConclusionThis was a perfect fit for me getting ready for summer mining. I was able to run it at a under clock making it a very efficient miner. The heat exhaust is manageable even though winter is over for me. The install was easy with use of the guides, no big surprises during my install. And only problem I had the support was great and nice to work with. It seems to be built with a solid metal case, and solid performance. The biggest surprise was how quiet this miner can be. It is the first miner I actually put in my bedroom and cannot hear it across the room. I have other miners from big and small, water cooled, and nothing is comparable on so little sound. I will keep it running and post how it goes overtime but it is a very good miner from my experience so far.
