It should have a pretty good lifespan..the aren't any parts in a small system like that there that are really prone to dying. Even if it doesn't, you're under warranty for quite a while.
BTW, I saw you were worried about refilling it. Sealed systems like that don't ever have to be refilled, so you don't have to worry about it. :good:
Thanks. Now I just hope that it does last for 2-3 years. By the way, I booted it up just a few minutes ago. Everything seems to be working fine for the length of time I messed around with it.
