I have put off buying a new PC for quite a while, so I have decided it is finally time to make a decision and have therefore spent a lot of time on SPCR lately. First of all I want to say how much I have appreciated the wealth of quality information on this site and forum, but I am still somewhat undecided on a few things (particularly PSU/cooling/VGA) regarding my new system.
First of all, the system is intended for J2EE/.NET development, number crunching, 24/7 operation and for watching HDTV, but NOT for gaming.
The parts I am pretty sure about are:
CASE: Lian-Li PC-V1000+
CPU: AMD Athlon64-X2 4400+
MOBO: Asus A8N-SLI Premium
RAM: 2x 1GB Corsair TwinX PC3200 C2
HDD: WD Caviar SE16, 400GB, SATA, 16MB
DVD: Pioneer DVR-110
DVB-T: Nebula DigiTV PCI
But, I have a hard time picking a suitable PSU, since I want it to be as quiet and efficient as possible. I'd like the Seasonic SS-400HT but this PSU does not appear to be available in Australia. The ones that are available though are:
FSP ZEN300
Antec Phantom 350 or 500
Seasonic S12 430W
I think my personal preference would be the ZEN since it is efficient and quiet, but it only has 300W. Which of these PSUs would offer the best option, considering that I am not intending on overclocking or use SLI. However there is a good chance that I will add a second video card for additional displays and GP-GPU.... which brings me to my next problem, the video card. It should be PCIe, have at least 256MB and have DVI for my Dell 24" TFT @ 1920x1200, and D-SUB since I have several CRT standing around that i would like to use. On the other hand I will most likely buy another TFT at some stage, so I'll need additional DVI, so if there are any cards with 2xDVI, one of which can be converted to analog/D-SUB, then that would be perfect. But keep in mind I don't want the card to be for gaming, just normal workstation use and HDTV.
And finally...which heat sink and fan do you recommend? Once again, quiet, no OC, and preferably without fan, as the system will be running 24/7 and I don't want to come home to a fried CPU just because the fan stopped working.
If that's not enough for you to think about, then feel free to comment whether I should get a SATA II for my apps/OS, instead of the WD SATA that I already have.
And most importantly

Any comments would be greatly appreciated.
Thanks, Daniel
