I shouldve put part numbers and stuff. Total cost for each of the 5850 rigs was around 1050 and then i added on a little for shipping and for installing windows license and all the goodies there. The 5850 was around 1100 so same thing there. I was thinking $1 per mhash was reasonable...
I was pretty accurate with my estimate then for the 5830 rig if you paid 130 per 5830 (I guessed 559+520=1,079). Considering your selling used you shouldn't be marking up the price 250 dollars. You can find every part in your comp right now or an equivalent alternative for the 1050 price brand new. As for setting up the os ect any one who is buying a caseless rig should be well aware how to do this with ease.
