Thanks to all -- great feedback.
I need to talk to my friend (he puts the kits together for me).
I believe that it is probably time (after 3 years) to upgrade the PC. The current box was not very powerful. For $500-$700 I can get an outstanding DYI upgrade.
I will likely get a PS locally as suggested and see if that solves the immeduiate problem. Id so, I can get at my information and tie the old/new PCs together, transferring the info that way. Then I can use the old PC as a server or to store pictures/music.
I'm glad to see that there is a simple solution to the IDE/SATA thing.
BTW - any better choices than Tiger Direct for barebones kits? New Egg doesn't have much.
I'll report back.
