Replying to Getting a new computer: Apple?

 I know a lot of you will just answer "yes". Because more than the majority of NS are obsessed with Macs. I'm gonna be honest I'm really not that computer savvy when it comes to specs and whatnot. I am aware of a lot of the things macs off though, and my home computer now...sucks.

So basically I need some guidance here. This will be replacing my home computer, so not a macbook or anything. So I'm thinking about the iMac. I have tons of music on my computer now, don't do too much editing but I do enjoy just fooling around with stuff when I'm bored. Since this is a home computer, there will be maybe 2 or 3 people using it at other times.

So should I just opt for the most affordable option?

2.4GHz Intel Core 2 Duo
1 GB memory
250GB hard drive
8x double-layer SuperDrive
ATI Radeon HD 2400 XT
-128 MB memory

Excuse my noobishness, I'm not very familiar with Macs yet and kind of just getting into it.

Thanks!
