The Lenovo ThinkCentre A62 is a powerful business PC with a reasonable price tag, but we weren?t thrilled by the drive caddy system and the amount of preloaded software...

Easily expanded and maintained, reasonably powerful
Quad-core processor
Energy Star 4.0
ROHS
EPEAT Gold and Greenguard certifications
Power hungry, drive caddy system is complicated, excessive bloatware
Uses a little more power due to quad-core processor
Could use a bit more multimedia performance
