Building a Mining Rig, Maximizing hashrate by lowest possible price.

[JohnnyPierce]

Hello, I want to build a new mining rig, at this moment I only mine with my gaming PC which nets me a maximum profit of about $100 a month.

I'm limited in funds however, have approximately $1000 to spend, what kind of equipment should I purchase to maximize my hashrate at the lowest possible price?

Please if you may share your gaming PC config because based on my readings GPU is profitable any longer. ASIC is the way to go and the lowest cost I found from a reliable company is the Butterfly.

However even with 5GH/s you aren't competitive.

I don't mine Bitcoin or any other SHA currency, I'm only focused on Scrypt alt coins such as Doge, LOT, DGC, Tips, etc.

My gaming rig currently has two R9 270x cards, which like I said earlier, are profiting me about $100 a month. I want to maximize this profit but I only have about $1000 to spend, hence I'm looking for advice on which sort of equipment could render me the highest hashrate at the lowest possible price.

Johnny,

There's a few things to focus on. Motherboard, cpu, and ram together, and its price per PCIE slot, psu price per watt (750w's are usually lowest here aside from getting a 220v server psu but those can have more headaches to get running), price per riser card. and finally price per card.

I'm running an asrock fatality mobo with 7 slots (not fully populated), my price per slot is $32 + risers.

Best card for ROI, 270, or newegg special on one of the 7870's. Build the rig on a boltless shelving unit with 12" deep shelves and use aluminum angle to hold the cards.

I'm not understanding what you mean when you say price per slot?

Sorry for the late reply, price per PCIE slot on the motherboard, or how much does it cost per graphics card on the system. If you have a $100 setup that holds two cards, then that's $50/slot, but if you can get a $100 setup that holds 4, then you will be at $25/slot.

Every time you have to buy another motherboard to run more cards, you also have to buy another CPU, RAM, and at least 1 PSU.

I would say a powered riser, a 280x, 290x or similar card and another power supply. And maybe transfer the components to an open air setup if you don't want the awkwardness of cards on risers outside the case. That's my plan anyway.

I have built dozens of GPU rigs to date, and the setup that gives you best mining yield for dollar requires 3 or 4 GPUs, currently the R9 280x. This will, however, cost your around $1800 to build.

What you can do, is create an excel file with all part's list and cost with automated calculation (I did that before), and it will be very clear what optimum setup you can get for $1000.
