I understand your intensions as I often try to complete/upgrade a system for as little as I can. But It seems that you are spending alot on this upgrade considering the performance you'll get out of it. It doesn't seem the best upgrade route considering how much you will be replacing. The big question I ask, is IF you didn't own the P4 1.4GHz cpu now, then what route would you go? That's the route I'd take as a 1.4GHz P4 isn't worth that much to hold onto. Honestly, again I think I'd sell off the cpu with the mobo/ram/case, etc. and look toward cheap Socket A or if possible, better yet,Socket 754. I'd probably only think of keeping that cpu if I was going to keep it real cheap and just buy a used mobo that could use your existing Ram, case, PS, etc. Tough call as I see both sides. Not argueing with you, just giving an opinion from the outside.
