If the issue is with the insurance, try to get more GPU from the insurance and then use cash to buy the MOBO of ur choice
GD70 is what one of my rigs is using. It's got 5 PCIe slots.


Consider this option.
 - GD70 (5 PCIe slot)
 - 1000W/1200 PSU (support 5x5850)
 - CPU of your choice
 - HDD of ur choice (If theres a need)
 - Casing of ur choice
 - RAM (2 GB + What u want to use)
 - a few other GPU from the balance of $1,800

Piece together a dedicated mining rig using the GD70+Sempron 140 [Purchase ur own], 2 GB RAM, PSU & GPU + Ubuntu/Linux on Thumbdrive (4 GB) [For 5 GPU get 2 PCIe Extender for $9]

As for your own computer. U still have Casing, CPU of ur choice, RAM, HDD & GPU (Assuming you got 3 or more from the insurance). All you need to buy is MOBO and PSU.

You'll get at least 2.5 Ghash/s with a working computer of ur liking + dedicated rig (naked or cheap casing). (total around 5~7 GPU) With a bit more investment.

This sounds great, thanks so much for the info!  Yeah this computer is completely dedicated to mining.  I have a couple followup questions:

  • How much power might this draw?  What should I do to the appt I'm in to make sure I'm not gonna blow things up?
  • Will 5x5850's fit in the altec 1200 case?  Any tips on what will hold all of this?
  • Do i need to crossfire anything? or can i just specify the gpu on 5 different miners?

don't buy that expensive motherboard. just get a cheap one, and use risers/extenders to utilize all the pci-e x1 slots. Also, you're wasting money with your i7, just get a AMD motherboard + cheapest CPU.

Everything i said above only applies to a dedicated miner, if you're using this for gaming, this build looks decent.

Yeah good point, thanks.

How does this insurance work?
You don't get to keep the full $1800?

From what I've read that MSI board should handle quad crossfire at x8 speeds.

Yeah, it has to be a replacement of same value (which I'm claiming at $1800), so I'm pretty sure I can't swing multiple computers.  Plus I don't have that much room/power  Wink
