Laptop (assuming used): ~ Bad: For the most part NOT designed for 24/7/365 operations
It may not be designed for it, but after years af running laptops for 24/7/365, I can tell you it works just fine in most cases 
Just keep the fan clean, and stay away from the ones with power hungry CPUs.Me too, I have a pair of them that have been up just about forever 24/7 but it's still something to consider.
Also, with laptops if you do have to change the fan out it is *usually* more of a project then a desktop.
On the flip side if the AC adapter dies on a laptop it's not a big deal vs. taking apart a PC to and getting a new power supply.
