thx!

yes i know that the value decreased (also wrote that...) i'm just optimistic
ok 60% is really much... also if i estimate that the value is rising it won't compensate the rising difficulty...

i'm still waiting so lets see how the course is changing

Look at the thread of mining rig pictures for ideas.  A lot of people try to basically build a rail to suspend the cards a few inches above the rest of the cards.  There really isn't any standard way to do this.  If you're handy, you could build something out of wood or PVC.  If you're not, you could use a lot of duct tape and twine

The extension cables are probably best for you.  Basically the 1x slots are designed for cards besides GPUs, like NICs and soundcards.  

For gaming, these 1x slots would not work with a GPU.  For mining, however, we do not need the massive bandwidth that a 16x slot provides, so you can use the card with only the 1x section of the card.

Since the graphics card has the full pins for a 16x slot, you would have to file off the right-side of the 1x slot so the card will physically fit into the slot.  

You can either get a 1x-->1x extension cable, then file the end off of that, or you can get a 1x-->16x extension cable that you won't need to file.  

The only way to get a bunch of 16x slots on one board is to get a higher end board like the MSI one everyone here uses.  If you do this, you'll have heat problems anyway, so probably best to start with 2x cards in 16x slots then add more via extension cables away from the other cards if you want to expand.

Video cards are designed to go into the long slots (PCIe x4,x8, and x16). But you can buy cables that allow you to use the short slots (PCIe x1) for mining. Or you can take a file to it.

>This is a plausible scenario.  What cracks me up is the people who assume the BTC exchange rate will stay the same forever   Look at >the historicals.  It's only going UP.

What cracks ME up is that people think prior performance predicts future results... actually it does not crack me up - it makes me sad...

its late to invest ,imo.

No.

300MH/s = .67BTC/day
= $5.70/day
= $171/month

And anyone with that kind of MH/s is probably using no more than 250w of electricity, so 180kwh/month, or about $18 more in electricity per month.  Well, if you get decent rates on electricity, anyway.  $72/month at most though.

Mining is far from being unprofitable.  When difficulty hits 4M, then we'll talk about it being unprofitable for a good portion of hobbyist miners.

this only works if your server has a graphics card. if you're going to mine with the CPU, don't bother, because it generates very little bitcoins.
