He never specifically mentioned GPUs. I'm setting up a remote rig for FPGA/ASICs, and there's still a lot that goes into them. Setting up your network, compiling CGMiner, auto starting CGMiner on startup, restarting on crash, etc. I'm still not quite familiar with setting up watchdogs, but that's next on my list.
While that's true, he did say:
Can anyone recommend a source of instruction on how to build a mining rig? I have some knowledge on the components that are required, but have never actually built my own computer before. I would particularly need to know the process of installing the necessary software to integrate the components with the operating system, along with whatever mining software may be needed.
The highlighted parts are what I based the rest of his post on, which makes me think of GPUs, considering you don't build FPGAs/ASICs into a desktop. Also, you don't need software to integrate the FPGA/ASIC units into the OS like you do on GPUs. That was just my assumption though.
Either way, much of this information is just scattered in lots of posts everywhere. Just googling your immediate question should be enough to get you through step by step:
1) "Best video card/FPGA/ASIC for bitcoin"
2) Buy said items
3) "How to mine on a ______"
4) in reading info on this, you'll see pooled vs solo mining mentioned
5) "bitcoin pool mining vs solo mining"
6) Make decision
7) "How to setup _____ type mining"
"Bitcoin _____ unit mining software"
9) Download the software of your choice and configure with everything learned above
10)
11) profit... Or not, depending on the difficulty in the coming months
