It is good to mine now while most alts are bottomed. So that when everything goes mooning again, we will have something of nice volume to trade with.
- its not recommended to use a PC case (always hotter than open air)
- its not recommended to use nVidia GPU (less price/performance)
- don't pick fancy GPU with RGB lighting its waste of electricity and sooner or later you will got bored
- you don't need fast and large disk, 32-64GB is enough
- you don't need fast ethernet connection 100mbps is more than enough
- you don't need latest and expensive motherboard, what you need is cheapest motherboard with most PCIe slot, like asrock pro-btc (80$) or gigabye GA-MA770T-US3 (30$)
- you don't need fast ram, 16GB slowest DDR3 is enough, even DDR2 is enough
- you don't need watercooling or air conditioned room (300w of AC never enough to compensate >1kw of thermal generated by GPUs) , what you need is good airflow
- you don't need expensive fast multicore cpu, dual core cpu is enough, preferably choose lowest TDP CPU such as Pentium, celeron or atom
- you shouldn't and don't need to crossfire or SLI any GPU
my suggestion
- always use powered GPU riser instead of plug in GPU directly to motherboard (6-Pin PCIe powered Riser is preferable instead of molex or sata)
- pick highest efficiency in term of price per performance GPU such as Radeon RX470-4GB is considered most optimum
- pick GPU that has dual bios
- if available, pick single radial fan (the one that used by reference design card), instead of dual or tri-fan for durabilty and ease of directing hot air
- pick highest efficiency PSU, with most PCIe cable and 4-pin molex cables, PSU built for mining is preferred such as from bitmain
- don't ever daisy chain molex or sate cable for more than one GPU Riser
- never use less than 18awg cable for powering GPU preferable 16awg cables
- if you want to expand, choose PCIe Port Multiplier first, instead of buying another motherboard
- turn of unnecessary onboard device, such as audio, serial port, usb3.0, esata
- choose PCIe gen1 or 2 in bios, don't use gen3 (better compatibilty for multiple GPU
