Best DVD Burner brands
What video cards u people use (juss out of curiosity... I'm gettin my good old X800GT!!! )
A Good sized power supply
and anything else I may or should consider looking into... 
In the order you listed...
I've always used Asus boards (A7M266, then A7N8X and now A8V deluxe), but they happened to be the optimal ones when I was buying; they are generally stable and reliable, but expensive and only average overclockers. I would say get a DFI board for maximum OC performance or an Epox board for great performance for a cheap price.
Maxtor DiamondMax 10 300GB. Performance is fairly close to a Raptor and has much higher capacity/price ratio.
I like the Cooler Master Centurion 5 (what I have) and Stacker cases. Great cases overall especially for the prices, aside from CM's embarrassing engrish on the boxes. Cases are really a subjective thing though. Just get whatever looks good to you and has at least one 120mm fan port.
Audigy 2 value OEM. I have one - it was $47 back in February - and it has all of the features of the more expensive models except for the extra stuff (firewire, remote control, external header box). Only the OEM ones have an internal pin header for front ports on them.
I would say get a Venice 3200 or X2 3800 and overclock it. The 3700 is kind of right between them, but the 3200 overclocks just as well and the extra cache on the 3700 isn't really worth the additional $100 or so in most cases. The 3000 is about as good too, but the 9 multiplier may in some cases slightly limit you.
The BenQ DW1640 seems to be the top one at the moment. I have the older 1620 model and it works great, both as a reader and a writer.
I have a BFG 6800GT. It has a pathetic custom heatsink, but overclocks well nonetheless. Fantastic in older games, but limited to 1280x960 without AA in most newer ones. I guess it has after all been over a year since I got it. I want something better to drive this monitor, but I don't think it's worth upgrading just yet since that would mean also mean a motherboard change just for PCIE and I won't have a lot of time for heavy gaming until the winter anyway.
I have a OCZ Modstream 520W and it's excellent. The OCZ Powerstream 520W has come down in price though and may be a slightly better buy overall. Enermax also makes great PSUs that have beefy 12V rails too; last I checked, there was a 465W one on Newegg that looked very good for its price.
As for the poll, nvidia for the reasons I gave in your other thread. Only a slight preference though.
From the early indications, they don't seem to be that great. They're going for the limited run at high speeds over higher yields with better tech.
