Recommend me a motherboard/CPU/memory/case please!
 

time for a major upgrade, due to longstanding issues,

http://bbs.scoobynet.co.uk/showthread.php?t=325728

so I want

1. named motherboard with online support to download new BIOS, drivers etc. Motherboard needs to support USB 2 and Firewire if possible
2. decent processor - use the PC for making DVDs from DV camcorder - not the latest and greatest necessary. Got XP 2000+ now which seems ok
3. at least 512mb memory??
4. Decent case - always gone for cheap cases before, are screwless ones much benefit?
5. Reasonable graphics card
6. Must be able to run Doom3 when it comes out ;)
7. Is it worth getting at least a new hard drive? Got a 40gb and 80gb in there at the moment, both ATA 100 I think, probably

I've got a ATX Ultra-Quiet PSU 300W AMD Approved - would that be ok to keep?

cheers,

Greg
