Wish you guys were in the US. Shipping time and cost is way to much.

We are looking at it - unfortunately the costs of operating in the US are exhorbitant; moulding costs, warehousing, staff costs, and a metric ton of costs associated with compliance. We'd end up having to nearly double our price to be profitable. The only benefit would be faster shipping to our US clients.

Any plans for a 10 blade + backplane frame?

We'd love to - can you link me to tech specs of the blades and backplane so we can take a look at the fabrication requirements?

I'd be interested in a couple of these, also.

These look pretty nice! I wouldn't want to stack them though since heat rises

We've done quite extensive temperature measuring on stacks that are 5 rigs high, and we've noticed that the heat dissipates as it moves upwards. The cards at the top of the stack are definitely running several degrees warmer than the cards at the bottom, but there are two ways around that:

1. Reduce the ambient temperature of the room. The cards will naturally sit at 73° C - 77° C without any additional airflow; lowering the temperature of the room by 10° C makes any rise (of several degrees) inconsequential.

2. Bolt a box fan at the back of the rigs higher up in the "stack" (or use a free-standing, extendible floor fan) to move the hot air away from the rigs.

Edit: just to reiterate, this isn't some magical solution that removes the need for temperature monitoring and additional fans, it just reduces the box fan requirement for most of the rigs and lets you focus on cooling down those that are running unacceptably hot rather than wasting power on myriads of fans.

I believe they are from South Africa! I managed to pull the trigger on a stack-able one.

Spot on - thanks for answering the question in my absence:)

I'll order two cases if you can make it fit a rack with rails. ;-)

sure, add me too! rack compatible rigs are being requested a lot

Peace of mind?

Sure, but we've got to remain cost competitive too, and the ATX standard allows for ISA-size cards to be supported entirely by their front bracket, so card manufacturers build accordingly. Take a look at the steel bracket and how it's attached to the card - that is NOT coming off purely by the weight of the card. We run Arianna barebones grids where the GPU is just bolted on to the square bar at the top, and we've never had a card fall off or break or be damaged. The additional GPU cross-bar on the consumer-grade design *is* for piece of mind:)

See what I said to aznatama above - the cards are solidly supported on that front bracket, and in all our testing we haven't found a reason to support the GPUs at the back just yet:)

Peace of mind?

I see the support for the other end of the motherboard. That should work. I have different length graphics cards in one rig. I use a piece of ready rod with a piece of cpvc pipe over it placed under the card about a half inch behind the pcie connector. My setup works, but it looks poor and is a pain to move. I am open to other options, but I want to be sure before I spend the money.

Also in the standard case the pcie slot/ motherboard supports part of the load.

Mobo has rear supports (not sure about center). You can see these in the other pics that don't show the mobo.

As for the GPUs, it does appear that it only hangs/is supported by the L-bracket. Most GPUs have braces along the edge that's bolted to the L bracket, so this should be sufficient. Especially since it's mounted vertically instead of horizontally (in standard case). However, I would do something to brace the rear of the GPU as well. (hard to provide for this due to different length cards).

Thanks so much for answering this whilst I was asleep! You're spot on - motherboard is supported on the front and back. It's hard to create tons of airflow and still have a full ATX plate, and it's also reasonably unnecessary for something like this in my experience:)

On the GPUs - we've played around with rear braces, and after a ton of fiddling we just keep finding it unnecessary. In our last test, we plugged and unplugged the DVI cable 500 times over a week without touching the card to brace it, and it was 100% fine. The GPU clips at the bottom held it in place and provided the additional support. I think the DVI port will wear out before anything else happens from a structural perspective.

All of the rigs that I have made support the back end of the cards. It seems to me that way would put too much tension on the cards and motherboard. Anyone have any thoughts or experience relative to that mounting style?

Thank you.

That depends on how quickly our supplier sends the aluminium extrusions to us - typically just a few days:) You can our delivery and returns policy on the link at the bottom of the page to give you an idea of worst-case-scenarios:)
