Conclusion: This is not the most exciting PC on the market, but like others in this segment it proves that you can have both power and energy efficiency. Think of it as the Toyota Highlander hybrid SUV of green PCs.
Pros: EPEAT Gold and Energy Star 4.0 certifications. Room for expansion. Energy efficient. Several form factors available. Easy-open case. Tool-less expansion. Internal power supply. Data redundancy/backup.
Cons: 800-MHz RAM for $20 more would've been a better choice with the motherboard and the CPU's 800-MHz FSB. Many workers don't need the extra expansion or tower configuration. Only VGA out.
