So here's what I have in mind.

--------
Case: Antec Performance One Series P190 +1200 DX ATX MT.
CPU: AMD Phenom X3 Triple-Core Processor 8450.
Mobo: Asus M3A32-MVP Deluxe Motherboard.
Card: ATI Radeon HD 3650/ PCIE 2.0/ 512MB DDR2/ DVI & HDMI.
Disc: LG 22X DVD RW +- Dual Layer.
PSU: (See below.)
--------
$811 CAN + approx. $50 shipping and free fans/wires/installation for/of the above components.
The RAM (XMS DDR2 800Mhz) and HDDs (x2 750GB Seagate) were salvaged from my old PC, and the PSU (x2 500W Antec Tandum PSU's) is included with the case.
I want this computer to be cheap, hold me over until the Deneb CPU's come out from AMD, get me gaming at reasonable frames for semi current games, and still be nice as a media computer for the living room once I move on to the Deneb system for my final gaming rig in the near future. I also plan on possibly using the motherboard/RAM/case from this computer in my next one, depending on what's nicer, compatible, and available (my reason for buying such an expensive case/mobo.) I may get another one of those ATI cards for Crossfire aswell, they're only $60 and supposedly perform great for that price.
Onboard optical support is a must, since my stereo is optical. Video card must support HDMI since the television in the media center is a 1080P 52" LCD.
Ideas?
