I-W if you like building computers, just about any distro will do. Funny... When I first started with Linux back in 2002 there were just a handful of distros. Now there are hundreds!
Distrowatch keeps track of what they're all doing now.
On the other hand, if you just want a Linux machine, Dell has great deals on
Ubuntu Linux machines and you know the hardware will already work without much configuration or tweaking. Of all the distros, Ubuntu seems to be the most user friendly for new users.
A word of awareness just in case you don't already know: Linux can mostly be used the same as Windows but is a more "hands on" operating system. Think of Windows as a Cadillac Limousine, complete with a chauffeur who will drive you where you may or may not want to go, all in creature comfort. Think of Linux as a street/strip hot rod that you wrench on and drive yourself. Both have their place.
The payoff with Linux? A cost free, rock solid operating system that hardly ever crashes with a wide range of free applications and programs. Added bonuses are:
* No viruses, Trojans, worms or miningwear (thus, no need for McAffee or Norton) and defragging and blue screens are a thing of the past. Having such a system requires a little more work and effort.
If you decide to take the plunge, stop over at
Linuxforums.org. I've been a Mod there for years as "Dapper Dan." We have a great bunch of folks who will give you good advice and solutions. We don't put up with flaming or trolls so you'll be in a nice hospitable environment where very knowledgeable Linux users are ready and willing to help.
* There actually are Linux viruses that have been created from time to time but none have had any real impact. Your chances of getting any are pretty close to zero.
