Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

Lots of interesting designs/concepts in here, ranging from messy-all-over-the-place setups to neatly organized racks. Mine use to be inside just a normal case, but temperatures got too high so now mine is the first option I mentioned haha. Takes up so much dam space.

I have only seen neatly organized racks stay neat and neatly organized racks become a rat's nest of ethernet and power cables. |

We may be brothers from another mother. HD also sells tubing that fits snugly over that threaded rod if you're nervous about the exposed conductors. With creative routing and additional support, you can get five rigs onto full-length verticals of uncut threaded rod in the lengths available at HD. Oh ... what kind of tubing? How strong is it? Sounds like you are referring to some kind of plastic tubing? I got some really thin wall aluminium tubing that I used a tubing cutter to make 2.2" spacers so I wouldn't have to use so damned many hex nuts. The result is questionable, it certainly has extra rigidity good for supporting 6 dual gpu cards (5970,6990,7990?). The design in the picture above doesn't have a whole lot of extra support on the outer most cards. The problem with the aluminium tubing is that it doesn't sit on a #6 washer very well. I was putting a washer between the extender pcb and the spacer and when I tightened the nut down on either end it did not straighten like I expected it to. Plus there wasn't enough thread on a 12" peice of all-thread with nut, washer, pcb, washer, spacer, washer, pcb, washer, spacer. So I removed all the washers except the ones on the outside ends. Tightened it up and it looked good, but the spacers ends are not much bigger then the pcb hole and they are rather sharp from the tubing cutter so I'm a little worried about extra strain on the pcb. Then again aluminium at this wall thickness is very very soft and it probably just flattened against the surface of the pcb. I plan on placing motherboards so that I extend the back plane and can use a union to join one set of rails to another so I have motherboard to motherboard support while still allowing me to move 6 gpu segments off the rail for motherboard replacement, whatever. In all I'm not totally happy with the aluminium spacers (not stiff enough), nor the zinc plated all-thread (too flimsy) or the 4" 6-32 bolts (too short) I'm using for posts. Plus I'm worried about corrosion and honestly I'm not a fan of cheap steal bolts. So I'm reworking the design to use stainless all-thread with stainless lock nuts and no bolts. I also want to use 1/4" stainless tubing, it's bigger and man is it stout! Dual gpu cards will be no problem. The only non-stainless is the aluminium L bracket supporting the rails. Also stainless + aluminium is a good combination. |

What super cheap method did you come up with for water cooling. All in all everything you have described is identical to what i'm doing, telco rack and all.

My main/standalone machine. 4x5830 gets about 1.25ghs not the prettiest, but its ultra portable lol get another 200mhs from the 5770 in my everyday computer when i am not using it.  got my killawatt today finally lol, this draws 750 4 cards all at 950/300 sempron one stick ram bamt on usb 2 120mm fans |

I have two rigs that are very similar, but run intel parts: 4x5870 950/170 / MSI H61m-p21 / G440 / 1G Ram / USB Stick / 2x 120 Fans / etc... With all of the cards on stock voltage it pulls 766w and produces 1832 mh/sec. Are 5830s that much less efficient? I have one 5830 in a really basic computer I used for other things before mining, but I haven't measured the power draw on it yet. |

You've got to have serious HVAC...
The winder was a breeze, I punched through the wall to an abandoned 6 floo elevator shaft. I pump the heat into the shaft, then bring in cold air from the shaft (Shaft is not insulated). Beautiful temps all winter. Now that it's summer, I simply only vent into the shaft, that air is replaced with cool air from the HVAC. The HVAC is set up to create positive pressure in the server room, thus the exhaust of the hot air balances nicely. |

The HVAC is set up to create positive pressure in the server room, thus the exhaust of the hot air balances nicely. I'm sure the building owner and local Fire Marshall are quite happy that you punched a hole through a 4 hour fire rated wall to exhaust hot air to save on cooling costs.  |

Not to mention that the server room will be the first to go up in smoke if there is a fire on the ground floor anywhere near the elevator shaft. |
