The last pieces of my computer have pretty much come together.

Memory is running properly in dual-channel mode, something I had worried about.

Got the SATA cable for the DVD-R/W drive and yoinked the VLC Media Player to watch DVDs.

Dual monitor mode will be enabled as soon as I have better positioning for my CRT, but I know it works without a substantial framerate drop for most applications I've seen.

Sweet.
