<< I like the Radeon 8500LE (OEM Version). It offers a good price/performance ratio. Alternatively, the GeForce3 Ti200 offers performance near the same level. I think either way you will be pleased. >>
Beware--the LE has crippled memory and lowered speeds, so if you're prepaired to spend a bit more (which you are, given your budget), get the retail 8500. The Radeon 8500 has a very rich feature set and fantastic 2D.
<< If you have a 5.1 speaker setup, the Phillips Acoustic Edge will most likely offer you the best sound quality. If you have anything, the Turtle Beach Santa Cruz looks to offer the best sound quality. Both cards seem to have solid drivers. >>
I concur--though if you want a nifty extra, you could try the Game Theater XP.
<< Make sure to get some high quality memory. Crucial memory is a favorite on these forums. With good reason. It is some of the best memory you can buy. It is also priced pretty reasonably. Especially since AT forum users get a 15% discount. >>
Another option (save the super-performance Corsair I recommend) is Kingston memory. Kingston is known for very high quality memory, and it is cheaper than Crucial.
<< The motherboard debate is really hot right now. There are a lot of choices for both the P4 and XP. I don't want to get into it too heavily. I'll just say I love my EPoX 8KHA+. =) >>
Be wary about the EPoX--while it is a good board, some have had stability issues when overclocking.
<< I would suggest an XP 1700+ or 1800+ for your CPU. They both are priced competitively. Both are fast. On the P4 side of things the 1.7GHz or 1.8GHz look pretty good. Just make sure you get a socket478 variant so you can upgrade to a Northwood down the line. >>
There is no reason to buy any P4 that is not a northwood cored one, due to its low performance on a clock-per-clock basis.
<< Make sure you get at least a 300W PSU. A 350W would be preferrable. Make sure it's from a good company as well. I would consider Antex, HEC, and Sparkle some of the best. >>
Given the future, stick to 350w. The recommendations for PSUs there are outstanding, and you should not listen to the hype about Enermax--it's not great.
<< The case is of little importance. Just don't go generic. Also, make sure it has enough expansion room for all the drives and such you plan on getting. >>
I disagree. You'll want a case that's easy to work on and well-ventilated. Look for a case with removable drive cages and that has drive rails, and the case should also have adequate airflow. A very nice plus is a slide-out motherboard tray (sliding with the cards, as well).
<< For harddrives, I like the Seagate Baracuda IV. They are reliable, fast, and quiet. >>
No argument there--though remember that the best performing ATA HDD is the Western Digital WD1000 special edition (the one with an 8mb cache).
<< For a CDRW, go with Liteon. Cheap and effective. >>
This is inadvisable, as Liteon CDRWs have some issues. Plextor makes some good drives that aren't too expensive, but if you want real performance--you have to buy Yamaha.
<< I believe I have covered most everything. Good luck! >>
You forgot about the HSF. 😉
For the HSF (unless you want retail), I recommend the Alpha PAL8045 (if your mainboard is big enough and has enough room around the socket), the Swiftech MX-462 (highest performance, but again, requires a lot of space), or the Millenium Glaciator2 (right behind the Alpha, very quiet, and works on any socket A mainboard).
