Phenom X4 9600 2.3GHz 2GB 250GB DVD±RW DL refurb from geeks.com $209.99. Built to lay flat so it fits the entertainment center and looks like any other piece of A/V equipment. Also picked up a 2TB Western Digital HDD for $60.
Last and best for me since I still have a lot of HD DVD movies is a LG GGC-H20N 6x Blu-ray BD-ROM/HD DVD-ROM/16x DVD±RW DL SATA Drive w/LightScribe for $60 again from geeks. I'll replace the DVD burner in the computer with this so I can watch virtually any HD or SD format.
$370 and I've got a rocking media center with plenty of storage space, can play virtually anything HD wise both audio and video. Can't wait for it all to come so I can hook it up.
