What percentage of downtime are people averaging over the past few days on Deepbit?  How does it compare to other pools?  Deepbit is the only one I've ever used but really looking like I need to switch.

What's "1 rig"?  That could be a $300 barebones system with one 5830.  

You say $2800 for a rig.  I guess you could spend that but it sure wouldn't be average.

Your electricity cost is WAY low.  A $2800 system would be like 4x 6990s and drawing close to 1.5kW x 24hrs/day x 30 days/mo = 1080kWh.  That would be $108 in the cheapest parts of the USA, $162 where I live.

Overhead/rent - different for everyone, but irrelevant unless you are renting a place specifically for mining, and then you can't calculate it per system since it's mostly fixed costs and doesn't matter much if you have one or fifty systems.  The only overhead you should have at home would be air conditioning.

The very first computer you set up may take close to 15 hours if you have to learn everything from scratch.  After that I would say 2-3 hours max, and then maybe 1 hour a month of monitoring/rebooting/etc.

You can probably get a sata to molex adapter and then hook that up to the pciexpress cable.  I'd be worried about 750w being enough to power 4x 5830s though. 

Each video card should come with two molex to pci-e adapters.

It still doesn't protect you in the instance where the account of someone with high feedback is phished and used to buy your auctions.

Selling anything intangible on ebay is a bad idea to begin with because of the risk of paypal chargebacks.  Even if you pull the selling a flash drive that just happens to contain BTC scheme you still will be unlikely to win any chargeback from a scammer.  Ebay/paypal always side with the buyer in any case and you can bet the person handling the dispute won't bother looking into exactly what bitcoin is before rendering a verdict.

I saw it hit 18k volume with a weighted price of 21/btc.  That's $378k in 15 minutes.

The volume is huge over the past 15 minutes. It's at 15k and rising, which is 1/5th of the total for the day.  Someone is unloading a ton of BTC really quickly.

Buying from Europe might be the thing to do now.  You need to pay exchange rate fees and tons for shipping, but you avoid things like VAT so we might be able to import them cheaper than the locals can get.  I'm just not sure about the laws and regulations if you ordered a bunch.

Difficulty follows price, not the other way around.

LOL, I through a sale order up at around $34/btc yesterday which was like $5 over Mt Gox at the time.  Today, the Mt. Gox exchange is down like another $4, but someone still bought my coins.  Didn't see exactly when the sale happened but it must have been $8 to $9 over spot.

I wonder how many of the old timers are finally starting to cash in their bitcoins.  Would it be possible to match the sales data to block explorer data, or does the fact that they are intra-wallet transactions stop you from doing it?

Wow, can't believe I never thought of using a shelving system like in that picture.  My shit is just all of the floor.  That would be much cleaner.

Is this going to turn into the bitcoin equivalent of Six Degrees of Kevin Bacon?

I think I have a problem in the making.  My circuit breaker would occasionally start buzzing, but it never actually tripped.  I have been counting on the assumption that the circuit breaker will trip if I have too much plugged in so I thought it wasn't dangerous.  But just adding up the wattages on everything that's plugged in gets me to like 2kW when it's all on a 15A breaker, so I'm sure I'm overloading it at least a little. 

The buzzing isn't constant or anything, and I will eventually move some of the equipment once everything has been built, but should I be worried at the moment?

Ahh, there the transactions are.  Fear alleviated, thanks.

I was having some issues with my windows computer which had a couple of bitcoins on it.  I sent them in to Mt. Gox last night, and it looks like it went through because it was deducted from my account.  I then tried to start fixing the computer, but things are worse than ever right now and I can't boot into anything.  Nothing has shown up in my Mt. Gox account yet and the transfer didn't register on bitexplorer so I'm worried it never went through, and worse yet 24 hours will pass soon so the address they went to might be no good.

I think maybe because I restarted soon after sending it never entered the block (but I'm not positive on how this works).  I saved my wallet.dat folder, installed bitcoin on another computer and put it in there.  It doesn't show any balance or any transactions so I'm not sure if it's even recognizing it.

So I guess I have three questions: 

How do I restore a wallet on a new computer?  I just put it in the bitcoin directory, not sure if that is correct or not.

When I do restore it, will it keep my transaction history and hopefully confirm my transaction which hasn't gone through yet?

Finally, what happens to coins sent to a Mt. Gox address after 24 hours assuming I don't get things figured out before then?

I'm starting to wish I had outsourced my mining after spending a few days building computers and still being less than 50% capacity.  Pain in the ass.

Those both say 7 expansion slots.  Does anyone have any experience fitting four GPUs inside?
