I've priced it out before, but here's my estimates for my line (likely similar to Crypto's)::
Motherboard: $80-90
RAM: $30
PSU: $110
CPU: $40-50
Graphics Card: $740 (I do 2x7950 builds)
OS: $100
Case: $90 (doesn't apply to Crypto)
Not sure how people do such cheap builds, but I would certainly love to see their parts list, I could really slash prices on my miners
I think they may be considering just the cost of the GPUs, perhaps they have some spare Wattage and PCI-E 16x sized slots. Not sure.
AMEN!
I use the 970 extreme 4 MOBO so thats $100
And my power supplies in the TNT models are 1250w Seagates, so they run around $230.
2 of my models actually do come in a case, but most people opt to have them open air anyway.
Yeah, I thought of going case-less as well, however I wasn't sure how shipping would work. I chose cases with good ventilation and a side panel that can be removed, so non-reference-design cards can ventilate from at least two directions very well. 1250W Seagates, talk about longevity.
Milk Crates with a mounting bar over top, keeps them nice and cool, and allows plenty of space.
