I have a similar system. I bought a raid card $29 SiL 0680 1 Maxtor 60GB 7200rpm 1 WD 60GB 7200rpm (Striped=raid 0) The best raid card is High Points: Rocket Raid 133 ATA133 for around $74 I have a 400Watt Enermax PS Dual 1.9 Ghz MP on a Tyan 2640 2x512Mb Kingston 2100 Registered ECC and ATI All in a Wonder 8500DV 64Mb Rendering is no problem. I've used Adobe Premiere 6.0, Ulead 5, and Windows Movie Maker. Premiere reccomends 10Gb on a minimum of 7200rpm HDD. (with raid you could use 2 5400rpm drives) So check your PS 350+ System temp? around 32C, CPU under 60C (Vulcano 9 around $17 keeps mine around 40C) 7200rpm HDD Minimum of 512Mb RAM Swapfile not on same drive as video (unless raid) I recommend a Hardware raid 0(striping) setup for the video and swapfile.
