Where are you from ?

It's easy to avoid custom in EU.

Hello all,

Im brand new to the forum and joined to ask for some opinions and feedback. We just placed an order for 60 Avalon 741's (if it's ever processed by Steve ), and are planning to build a small farm with them. (we also ordered a couple L3+'s, four S9's and two D3's so far, but thats another story).

We hope to run ~55 Avalon 741's at any given time with plans for another bulk order, hoping for about 40BTC/year for a couple years while we can (insert sarcastic 'HA' here)

We have a steel prefab warehouse available, approx 750 sq-ft. We're installing a dry fire suppression system, 24hr security cams, there are guards on the compound, 30,000 btu HVAC with filters and exhaust fans.

I was told the warehouse is connected to 300w 3 phase power and is wired for 220v (IIRC)

Electricity is dirt cheap in my country (like 0.001 USD), and my business partner owns a fire/safety/electrical industrial (Oil/Gas) service company, so we have a certified electrician and network/IT admin assisting with the setup/networking.

I wanted to get some feedback/pointers/tips on:

Power Requirements
Network Requirements

Is there any special network hardware that may be needed to run 50+ miners? (or is it as simple as a simple LAN network, three 24 port switches and an internet connection??)

help an old guy out
Much appreciated.

did you use   a reducer  to shrink  the 6 inch fan to a 4 inch duct?

something like this?

if so  you will kill the fan way way way faster

you need to buy this  stick the fan end into it and a little of the metal  box seal it by wrapping the duct with a bit of duct tape

i used 5 inch flex ducting attached to fan (fan has 5inch diameter).
but already ordered 10 inch to replace it.

I sent two bank transfers for  four 741's and a controller. to:

Three of the 741's are running, right now and the 4th will be delivered Monday.

Just got notification that my two new avalon miners should arrive Monday. But my hosting place just informed me that they are full. Does anyone know of any reliable hosting with available space, preferably here in the US. PM me so as to not tie up the thread.
