Some one is selling it. Can you please advise me the reasonable price for the following rig and is it possible to get bitcoins/litecoins mined through it ? This is the actual advertisement

Mobo : Gigabyte 990FXA-UD3
CPU : AMD FX 8-CORE 3.1 GHz
RAM : 16 Gigs
PSU : 1200 Watt Enermax Platimax
HD : 1 TB Western Digital
GPUs : 1x Powercolor 6990, 2x Radion 6950 (I have both flashed to 6970)
Cables : 2x Powered PCIE 16x to 1x, 1x Non-Powered PCIE 16x to 16x

Most of the components are only a few months old except the Cards which are about a year old now. The miner hashes at around 1.7 MH/s for scrypt based coins (Litecoins, Feathercoins, etc...) I forget what value it's for Bitcoins and SHA-256 based coins but it should be around 10x more.. (have a look at dustcoin . com / mining) if want an idea how much you would be making... The frame has room for two more cards for later expansion
