The power supply will have to be replaced.
The case should be okay. Here are the dimensions:
7.2"(W) x 15.6"(H) x 14.9"(D)
Complete specifications and detailed owners manual are available at the Sony web site:http://esupport.sony.com/US/perl/model-documents.pl?mdl=PCVRS410
I took a quick look at the interior diagrams in the owners' manual. It's got a micro-atx motherboard with 4 expansion card slots. No problem finding a new one. Micro-atx motherboards are readily available.
