@Syldon and I run a file server that's now 16 years old, running Linux as happily as the day we bought it... of course, after it's had its CPU, memory and hard drives upgraded multiple times. For 3 times the price of a Mac of the same vintage and no idea after the upgrades.
I never meant to imply you couldn't get quality PC gear, you very much can, but as soon as you do you're paying just as much or more than a Mac.
The PC vs Mac debate was old and tired in the 90s and now it's just dead.
