PC for a Sony SACD 9000es VSE Modded unit?

Anyone with recommendations for a PC for my Sony 900es SACD player? It has VSE Level 6 Mods, which sound great, but I would like to try out a good power cord. Budget is around $250 new/used, and the local shop carries nothing but Monster cable.
I use a PS Audio Statement Extreme on my modded SCD-1 and like it very much; much blacker background (lowered noise floor).
