@hehemrin I love laptop servers. I run some, even. Two things, though.
One, if you need extended high CPU usage, you'll murder the fan. Laptops are best for things that just need to idle 99% of the time.
Two, consider ECC RAM, which I've found much more useful than advertised. It's harder to find a laptop with that.
@hehemrin I got some because the ZFS people scared the bejeezus out of me, but after running a bunch of stuff with and without, the difference in stability and lack of mysterious errors is totally worth the premium in my opinion.
