So I have a nice looking scrypt rig, built on a yellow Dimastech Nano Bench with a ASRock FM2A88X Extreme6+ mobo, a SILVERSTONE ZM1350 1350W, G.SKILL Ripjaws X Series 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 1866 (PC3 14900), Western Digital WD Blue WD2500AAKX 250GB 7200 RPM 16MB Cache SATA 6.0Gb/s, and an AMD Sempron 145 Processor.
The cards are 4 x XFX Black Edition Double D R9-280X

I'll get more pics up and a pic of cg miner when I get home. (selling the yellow one)
I've had this running at 2.8 MHs no problem for a few weeks... You can see I can only fit three cards easily, so I have the fourth card resting against a milk crate.
Anyway, one of the cards had one of the fans on it die... the rig still actually runs fine if I point a large fan right at that fourth card, but I have taken it out of the rig for now. So... I am running quite comfortably, all day long at around 700 KH/s per card, with card 0 around 84, card 1 around 76, and card 2 as low as 66. I am sure the card is still fine, and just needs some work on the fan on it.
Moved to ebay. Thanks for looking.
