I am hoping/thinking depending on time and funds about making the move to 64 bit... I don't really want to skimp and so probably will not reuse any of my components from my XP3000+ rig. I have come across this prebuilt which seems pretty close to what I would aim for and, by my rough calculations, the price seems so close I am wondering what I would get from my own build. Probably with my own build I might change the mobo (I think the site is less than specific and has a typo, must be ECS mobo). I did ask the seller about their PSU and it is the Hiper 420W dual fan silent model - that impressed me as it is the sort of one I might choose, excellent value PSU and with quiet options for when not gaming. Anyway - I am still at the toying stage and really would appreciate feedback on that particular rig in the context of build myself. oh yeah, and he offers a choice of case styles, nothing amazing, but hey to me this will be a box down under the desk it is how the guts work that gets me.
