For our company server that runs our website and programs we use:

# Intel Dual Xeon Clovertown (8 CPUs)
# 512MB Guaranteed RAM
# 2048MB Burstable RAM
# 500GB Bandwidth
# 50GB RAID-10 Disk Space


For our customers we use the latest technology as it comes about. Which means as we generate more customers and new servers we will purchase a server with the latest technology. The last server we got was a Intel Dual Core Dual Processor Xeon 5130 2.0GHz (Woodcrest) server which was about a year ago. Our next server will be a Quad Core Dual CPU Xeon 5405 2.0GHz w/ 12MB L2 Cache (Harpertown) or better depending on what's available at the time and is the latest technology.
