You're mixing a Radeon 9700 Pro with a 17" monitor? Dude. That's like, putting an 8-piston engine in a Geo Metro. What The Fsck? Upgrade your monitor to at <i><b>least</b></i> a 19", or downgrade your video card and save the money for when Directx9 games come out, and your entire system is right next to completely worthless. Seriously. No 17" montor looks even halfway decent at 1600x1200, and even 1280x1024 is strained.
I like the Liteon 166S's, but to each his own. It's not like the Pioneer is a bad drive or anything.

You didn't mention which case you were going to use...
Make sure the one you purchase has fittings for at least one exhaust fan at the back and lots of air intake openings at the front. You should use at least one exhaust fan at the back of the case. An intake fan at the front may help but isn't strictly necessary.
