Intrusion Prevention System - cost analysis
I've been wanting an Atom D510 desktop for some time, and thought I could finally justify one. The idea was to buy an energy efficient nettop to use as a network intrusion detection system (NIDS) / network intrusion prevention system (NIPS). The issue is I have several relatively fast systems (1.5+GHz) lying around the house.
The proposal: http://www.newegg.com/Product/Product.aspx?Item=N82E16856119024
Chassis: Foxconn R20-D2
CPU: Intel Atom D510
Chipset: Intel NM10 with Intel GMA 3150
RAM: not included
Cost: $130
Power usage: Estimated 22W
Using my trusty Kill-A-Watt, the following electrical usage statistics were obtained (system at idle, no excessive equipment removed):
HP: Estimated 57-60 W
Compaq: 74-75 W
Using the calculator at http://www.csgnetwork.com/elecenergycalcs.html, the annual cost to power based on $0.10/kWH are as follows:
Proposal: $22/year
HP: $53/year
Compaq: $67/year
Cost of operation, in years:
Nettop: 1=152, 2=174, 3=196, 4=218, 5=240
HP: 1=53, 2=106, 3=159, 4=212, 5=265
Both systems unsurprisingly utilize more power, but the initial cost of the nettop would only be offset after 5 years of ownership. In conclusion, there will not be a nettop netappliance in our future.
