Well, I feel underwhelmed as folks here are showing off ASICS...  

Anyway, Here’s my rig:
 
4 x MSI R7950 Twin Frozr III cards
 
Seasonic 1000W Platinum PSU
 
ASROCK 970 Extreme4 ATX Motherboard
 
1 x PCI-e x1 to x1 powered riser
 
3 x PCI-e x16 to x16 unpowered risers
 
4GB DDR3 RAM
 
120GB 2.5” HDD
 
AMD AM3+ Temash single-core CPU
 
Tubular square steel open chassis
 
Plexiglas baseplate
 
Windows 7 x64 Professional
 
CGMiner, VNC & Afterburner
 
 
 
Mines BTC @ 2.1GH/s pulling 850-900 watts from the wall
 
Total cost: about $1800-$1850

One of these days, (probably after ROI) i'll swap the PSU out for a 1200W unit and add another card. I should have bought a 1200 from the start.
