been messing around with rboxes... got 5 powered via the breakout board, then for the rest, I took the PCI-E 6 connectors for gridseeds
(from here:
http://buyahash.com/shop/pci-e-6-pin-3-gridseed-power-plug-2-1mm-dc-barrel-plug/),
cutoff the 2.1mm barrel connectors and soldered on the 2.5mm barrel connectors that come with each r-box.
using platimax 1200 PSU, powered up 17 rboxes using 771 watts. 21 watts idle, so (771-21)/17 = ~44 watts each. running at almost 35 Gh/s each, freq=290
waiting for that cool 3d printed case for the BA
they run quiet.
bfgminer coming up to bat soon.
edit: I think using that pci-e 6 pin to 3 barrels is the most cost effective solution. you probably have a psu already running something that has a spare pcie 6 connector, so powering up 3 rboxes is a no brainer and is THE simplest solution. alternatively, if you have no available pcie6 connector on a PSU that is already on and running I bet you have a spare PSU. the good ole paperclip solution + the pcie6 to 3 barrel connector is again most efficient and cost effective. buyahash will make available 2.5mm barel connectors on the pcie6 connector soon if you don't want to modify gridseed plugs yourself. it is fun however.
yeah the break out box is good if you want to run 6 to 10.
If you want cables-pcie I am having cablez make 2 sets for me each can run 3 r-boxes.. When all gear comes to me I will show six run with the break out box and 6 run with the pcie adapters

https://bitcointalk.org/index.php?topic=74397.msg7234870#msg7234870my goal is to resell these in 3 packs on ebay. what I want to be able to do is point new miners to a pool like bitminter.
I am hoping I can talk the good doc h into setting up a secondary pool for solo mining.
then tell people use 2 for normal pool mining and 1 for solo mining.
The current math for a month of mining with one of these doing solo is about a 1 in 610 chance to win a block.
by the end of the month it will drop to about 1 in 1220.
amazing if you pull out the startup price of 210 bucks for 3 and only figure your power cost at 15 cents a kwatt it cost you about 14.60 usd a month to run this.
the math is not too bad….. you are far better off buying 3 of these mining with 2 at a normal pool and 1 at solo then buying any usa 3 digits number
