These look hard to setup, as these are just barebone boards - also there is some mention about pool setup in the faq. I guess only for seasoned miners. I guess about 15-20 btc per board is fair price, given 3-module avalon batch 3 was about 76btc shipped.

There are some very generous bidders on that list.

So I've been seeing a lot of stuff about how BFL hasn't shipped people's ASICs yet. This thread isn't about that.
I just want some info about this:

Am I incorrect in thinking that 5 GH/s is 5000 MH/s?
At $274 (assuming BFL ever gets their shit together) isn't that an excellent deal?

Also, it says it needs to be plugged into a host computer. What part of the host computer does it draw on?

Google "BAMT", use windiskimager to make a bootable USB drive.  No muss, no fuss - don't even need the hard drive.  If you need to access it, try SSH from a laptop or even "I-devices".

Running 5 GPUs at a time shouldn't be an issue, it's been done before.

Try completely uninstalling everything with the AMD install manager. Reboot and search for any left over amd .dll files in system32 or other places. Delete them manually, there tends to be a few left over.
Reboot again. Check device manager to see if it's still showing error 43. If it is, uninstall the card through its properties menu and reboot. See if windows update picks something up (the found new hardware dialog?) Then, reboot again and try installing AMD drivers again.

I had the same issue when I was trying to use an HD5870 and HD4850 at the same time. Basically a shuffle of uninstalling AMD and Windows drivers eventually resolved it, and there was never anything wrong with the card or my motherboard.

The words "late" and "delay" are the closest BFL has ever came to being honest.

The Box of Felons Fans is quite an accurate picture though.  When they go bust and have an asset auction I really want a BFL Box of Fans as a souvenir.  My plan for it is to keep my switch and my router inside to keep it cool and maybe just a storage place to put an Android tablet on it that I would have playing a GUI like screen saver promising cool things like Time Travel or attractive 20 year old women who want to pay a middle aged man for sex.
