I have a loaded BTC1 coin graded ANACS MS61 that I would like to sell, but I'm not sure how to actually do it given the current value. I tried contacting a couple of auction houses to see if they would do consignment but neither of them ever replied to me. (Stacks & Bowers, and Heritage) Any tips?

My heating unit mounted on the wall. 3.5GHash @ 1700W

You need to acquire some cable management skills Smiley

F the cable managemnt.....  start hashing, lower clocks, keep hashing for long time.
Better cable management is better airflow is better cooling. Ever tried to wire up a whole rack full of servers? You learn real quick about cable management, and once you get into the habit of it it becomes second nature and easy to do.

Why do I always see Newegg boxes off in the corner of these builds? Yes that's right - because Newegg is AWESOME! Grin

This is my recently reconfigured rack of 5830s.  When I'm done with the others, I'll post them as well.

I spy with my little eye... a Lenovo 60 watt AC adapter. Grin

It looks like that arrangement is OUTside of your house, is it? I see an outswing door and a concrete step, as well as siding material.

My newest addition to my collection of rigs, my rig at work.

How does your boss like you running a rig at work?

I wouldn't see the problem. It's probably near silent because of water cooling.
Yeah and it looks like it might be replacing the heater below it with something that makes money while making heat. Wink

Epic Power Strip.
I have one too, somewhere. I have no idea how old it is, probably at least 10-20 years old. MASSIVE thing.

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.



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.   Roll Eyes
lol, I know right? 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.

Figured I'd share pictures of one of the mining racks..

8 machines, all rack mounted, corsair Power supplies, 890FXA-GD70, Athlon x2's 2G ram, 27 ATI/AMD cards mix of 58xx,69xx, PXE/NFS diskless, runs mid 9 GH most days. cgminer set to auto-fan 20%-100%, target temp 80C.

WIN. I like clean setups like that.

Since everyone is in the sharing mood today.  Cheesy

Mmmm, nice, I've been running numbers in my head about bitforce singles all day...
They pretty much win from all angles unless you have so many that you need to worry about cooling, and unless your power is way too expensive.

Yup, its outside. Why pay to pump the heat out of my house (air conditioning) when I can let mother nature do it for me? Been like that for at least 8 months with no significant problems.
No rain?
Or just sheltered some other way? It looks precarious, but if it has worked that long there isn't any reason to change it.

Just add a lowercase "L" after the imgur name before the ".jpg"


Is this works on other sites also? or only in imgur.com?
Only on Imgur.

whatever happened to scaling pictures down a bit?
My bad! copied directly from iPhoto.
Just add a lowercase "L" after the imgur name before the ".jpg"
For instance, http://i.imgur.com/e87ek.jpg would become http://i.imgur.com/e87ekl.jpg

You can also link to the large image like so:
Code:
[url=http://i.imgur.com/e87ek.jpg][img]http://i.imgur.com/e87ekl.jpg[/img][/url]

It would look like this:

2 rigs, 7 cards, 3 PSU's between them. Hazard waiting to happen. Smiley
Lol! I remember (ab)using a bunk bed in that manner, except that it was with Romex, christmas lights, and an old mechanical time switch. Definitely a fire hazard Grin

EDIT: Ah, I see the metal racking everything is mounted on, that is better than my setup where I used wire staples and fastened it directly to the bed.  Cool

Why not linux Smiley

Never used Linux before.  Yes, paid for my Windows licenses, sorry.  Rather not try to crack 7 and again it's the case of legitly using these systems for business purposes other than mining potentially that I want to look out for.
Sorry, I didn't imply that you ought to crack Windows, but rather that Linux would be more ideal Wink

Of course if you use them for gaming occasionally, then Windows might make sense. Dual booting is also a possibility.
