All of the above!! LOL
Seriously, I use a 2.2ghz Celeron, Windoze 2k sp4. 512g Ram (Burned out the other ram stick a while back) 300gig, 160gigSATA & 20gig HDDs. 128meg graphics card.

Oh! And I have patience of Jobe.

To speed things up, I set the wireframe to as low as I can (16), plop render a lot and keep my MATS as basic as possible until final render time.
I also have coffee pumped intravienously to save time.

Most of the stuff I've done so far on this project takes at most 5mins to render. At premium rates it takes no more than two hours.
Look out for another WIP in the next couple of days.

I found out that as it's my birthday soon my son is building me a new machine! My family couldn't keep it a secret because they needed to know what I thought of the specs they had decided on for me.
So, hopefully, a dual-core machine with 4gigs of ram, a 500gig hdd, a 256mb graphics card and a very fast burner is coming to a desk near me soon!!!! (Pants with excitement!)
