I would suggest looking at asics if you have to do scrypt look at ones currently out not pre-orders.
Do some ROI math chances are buying PSU and Motherboard will not ever pay off with GPU mining.
Thanks for your reply. My OP stated that I intended to mine only with the Triton (=ASIC mining), while reserving the GPUs for other tasks.
1) Having read through the 472 threads of the HashCoins announcement, I am indeed concerned about their delivery times for pre-orders, but I've looked around and I have a hard time finding a scrypt miner with a better ROI (36 MH/s / 144W) within this price range (I'm trying to stay under $800).
2) Moreover, I like the PCI-e format, the idea of having a rather powerful ASIC miner, "hidden" inside my PC. Are there any other scrypt ASIC miners in this format that are already available?
1) I understand what you are saying. Yes it does look good on paper but there is a chance you order it and NEVER get your money back or get the product. They mention Q1 2015 and they have no prototype Ive seen on this card, so it is not looking good. There are a lot more options in BTC mining. Scrypt most companies are not putting much R/D into it. Just does not make business sense.
2) No there are some old USB sticks, but not PCI-e asics for scrypt (that I have seen). A case just is not the perfect environment for a miner, it's why most GPU miners were doing open air rigs.
I hate to be the killjoy but I would look at a miner that has been shown to exist and is standalone.
