Yep. They do VERY well. My first was an old eMachines 433i, and it lasted from August 2000 to November 2003. Added memory and other stuff, and it did fine.
Then I got a new one. Never really considered another brand.
My previous model was the eMonster, purchased in 2000. First one was defective out of the box. The second model that they shipped worked like a charm until earlier this year, when the fan gave out and the system started to run sluggishly, even after a fresh format of the hard drive.
