Hi Alex. I recently upgraded my rendering computer using the same box(case) that I've been using for 4 years. I lucked into a small windfall and added a new Mobo, ram, dual-core CPU, HD, and Vid card. I got a great deal on an Nvidea 8600 vid card and while it isn't top-of-the-line, it runs all of my graphics and 3D apps with no problem, and this includes Wings, up to the latest version. I am using XP home still.  I got most of the parts from my local Fry's store.
