1) This is the wrong subsection for this post.
2) you are asking retail price for a used system.

These are new parts built two weeks ago. I cannot run from my location so I need to sell. I can give you receipts to verify.

I'd be surprised if that thing could run ANYWHERE thats above freezing temperature.. 3 7950s in a case that doesnt even look to have the side fans installed.. sweet jeebus that thing is gonna be hot.

yep... 24/7 two weeks of extra hot mining... maybe about 100-120 degrees?  :D

It has a top fan and a side fan. Actually does quite a good job of dispersing the heat.

how many MH/s does this ditch out ?

For which protocol? I know for Scrypt (litecoin) it gets about ~1.5 MHash/sec. For bitcoin you should see about 1.5GHash/sec

That PSU is borderline without undervolting. Three Sapphire for me pulls about 870w at the wall with stock voltage.

pfft 1.5 MH/s and it costs $1400...

that's so much

no way that thing will run anywhere.. I had 3 7950's in a case, Thermal shutdown EVERY time no matter what I did.  I had LOTS of fans on it.  Gave up and put it in a good old milk crate :)

2 cards if they are spaced apart nicely..

EDIT - just read you were getting 1500 out of them so I think they are clocked down.  Which will help with heat.  I am pushing almost 1800 out of my 3 7950's

Yup, probably because I'm not overclocking. One of the disadvantages of OCing is that the cards are not really designed to disperse the heat you are generating when you run at higher clocks.
