im building a system around an athlon64 3200, XFX GeForce 6600GT, 1 gig ram, 120 gb segate barracuda and a dvd-rw drive.

i want to put all this in a micro atx case with a 200 watt psu. will 200 watts be enough, or do i need something more powerful?

Probably will need more than that. Use this link:
<A HREF="http://www.jscustompcs.com/power_supply/" target="_new">http://www.jscustompcs.com/power_supply/</A>

to estimate your power needs, then add about 50% to allow a good buffer (most PSU's are rated at peak, and are made to run at about 70% of peak).

Probably will come up with 350 or more.

The Micro ATX case you're considering probably comes with an SFX style power supply (a miniature form of ATX). Newegg lists them as Micro ATX, allong with the PS/3 form factor (go figure), and has some with fairly high output.

6600 GT requires 350W psu. You may get it to run, but most likely you'll have problems. Once the gpu gets under load - it sucks the 3-juice.
