Also, VARDIFF would increase my payouts by like 72% or something... 

Yeah, poor h2o

Down to a measley 13GH/s where 3% goes to him... so now he only has 390MH/s going to his private account.  That poor sucker! 

You can't.  Guess OP got bored with the idea and decided to stop posting. 

I will be doing the anlaysis on that this weekend as well as coming up with some basic diagrams for assembly instructions, but likely they will be 30 units for a 10% discount, 60 units for a 20% discount, and 150 units for a 30% discount.


The current design is for allowing a minimum of 1" of space between GPUs and that is if you are using 8 cards.  Most GPUs are less than 2" wide, so the 24" base allows for 1" in between cards which, coupled with a box fan is sufficient head dissipation.

As of now the add-ons are going to be:
Stackable
PSU supports (one or two)
HDD/SDD bracket
pre-drilled ATX mobo holes
- plastic standoffs, if needed
- brass standoffs, if needed
pre-drilled GPU front screw holes
- screws, if needed
Box fan mount


I have custom-built a vertical rig, but have concerns about a mass-produced model as the size of the video cards must be identical or I don't feel the supports are substantial enough so all cards in a unit must be the same height or I must make the support bar seperated into adjustable parts which I don't find cost effective:

Edit:  In this picture, I simulated the size of the customers card with a block of wood that I cut down.  It is clamped onto the support because it was requested that I do not drill the GPU holes, so I had nothing to screw my Radeon 5850 Wood Edition into.

FYI, if you have no idea how difficulty and mining works, stay away from all pools... That is all...

Please show me evidence that he is not running or improving Middlecoin.

This pool has been around for seven months and there have been no hacks or attacks as far as I know.

What is so horribly wrong with Middlecoin right now?  We are having a couple of bad days and people are jumping ship?  Fine by me, but I'm too lazy to make a move every couple of days.  Unlike h2o, I don't give a shit how big the total hashrate is as long as my payouts are still consistent.  It's been my experience that the low days are followed by pretty nice ones, so I am just hoping history repeats itself in the near future. 

Understandable.  I'm working on bringing the costs down to where $200 has all the bells and whistles but $100-140 is still a really solid design that most people will have no problem using.

Edit:  also thinking about doing pre-orders to see if I can reach the order threshold for a 10-30% discount from the aluminum supplier.

This.  Times a thousand.

That's why I personally love h2o in the gayest way possible.  He is busy doing actual work (or lines of coke off a strippers ass) instead of sitting around the forms correcting idiots on the basics of mining and difficulty and their stupid fairy-tale-solves-all-problems VARDIFF.

Just wanted to point this edit out.  I was told by a friend that these worked just fine without being powered but that is NOT the case.  I have tested it myself and they will only work when the molex is plugged in.  Also,  I should have unpowered x1 to x1 risers coming in next week as well as the USB styled risers.   Website launching March 1st!

Why should he care about suggestions from people who use his pool?  Besides "make the website prettier" what suggestions do most people have to offer?  Are they going to develop a new algorithm to increase payouts?  If so, he is probably interested in that, but if someone had the ability to better his algorithms then they probably are a pool operator themselves.

As for concerns... what concerns do you think that could be brought up that h2o is not aware of?

I swear some people just think he is sitting in penthouse suite in Vegas doing lines of coke off strippers asses while collecting all these fees.  He isn't running the most successful (to-date) auto-exchanging pool by just sitting on his ass.  He gets shit done and it's obvious because the pool is still standing and still competing for the title of most profitable pool.

No.  I just am saying that I have never needed to contact a pool operator since I have been mining.  Just curious why people need to contact him? 

Who are these people that are constantly needing to be in contact with pool operators? 

You guys must have a shit load of hashes.

Yeah, no kidding... that clown better get on here and explain why my rejects are lower now than they were last week and why I keep receiving consistent payouts.

This shit is no joke.  This is my livelihood!

Welp!  Looks like the aluminum won't get here until Monday.

Going to be a relaxing weekend for me then...

OMFG THIS POOL IB SROKEN

I RECEIVED ONLY ONE PAYOUT EVERYDAY FOR NOW LIKE 18 DAYS BUT Y I CAN NO GET TOO PAYOUTZ

MY HASH SHOWS 2.2Mhz BUT I ONLY HAVE 2.012 MASHSES

FIX THE FUCKIN POOL US CAMMER

Man, I was just discussing this with my dad yesterday and he said no one would want that.  About to text him a screen shot of this... but yes!  I plan on adding a box-fan mount as I think that is the best heat dissipation solution outside of an actual data-center cooling system. 

We are needing to get the next order of aluminum before finalizing everything.  The custom orders were great, and we will definitely enjoy working on them, but I'm reserving some of the aluminum for personal use so we can tinker our designs and finally get some quality pictures up.  I am also working on turning sketches into assembly instructions.

After I get the aluminum I will be working on making 5-10 stackable base units so I can conduct some tests on their umm... "stackability".  I will not sell any stackable units until I am sure they stack well and have a recommended stack limit.

You are very welcome!  That is a damn fine rig you got there, man!

Quick update on price:

I am not entirely done with cost analysis, still needing to consider packaging and how to redo the pricing to a model that has add-ons to lower the base price.  The total price right now for a stackable 4-8GPU, 2PSU model, with pre-drilled ATX specification holes for the Mobo, 2 PSU support brackets, HD mount, and pre-drilled holes for GPU front mounts is going to likely be $199.

Of course, all of those features are optional.  You can throw down a piece of cardboard and forgo the mobo standoff altogether, and the PSUs can just rest inside of the case without any brackets - they fit nicely between the motherboard support tubing.  Twist or zip-ties can be used instead of the GPU screws, and SSD's or thumb drives can be used instead of needing an HD mounting bracket.

Right now I am working out a solution with the add-ons so that I can get the base price closer to $100 and then you can add-on whatever you want. 

Aluminum order update:

The aluminum supplier is currently out of the black tubing, so I am only going to have silver tubing and black connectors in stock hopefully by the weekend.

In the future I think I might get some custom colored connectors so that you can pick your own color combo.  I plan to have both silver and black tubing and probably three or four colors of the connectors. 

Let me know if anyone would be interested in certain colors of connectors.  Maybe silver tubing with Bitcoin orange connectors?

PM sent.

Out of aluminum for a few days.  In the meantime I am going to focus on assembly instructions for the base model.

I love the custom orders, though, they are a lot of fun!

What are you wanting to build?  Seems really cheap!  I'd love to be able to get my costs that low...
