The computer should have the possibility to run Linux, since of the features for multihead on GEM. So here I start with a Linux-Style self assembled computer. (Maybe someone can write some Mac-Hardware here too for comparision.)
Graphic-Card:
One solution is to use the profesional Graphic cards from nvidia with PCI-Express (see http://www.nvidia.com/object/IO_11761.html )
1) Quadro FX 4400 --
Best (14.2.05) now
- report in german on golem: http://www.golem.de/0408/32875.html
- features: http://www.nvidia.com/page/qfx_uhe.html
- cards ( Ifound for quadro cards only PNY ?-)
2) 2 nvidia FX 6800 SLI with SLI Board
a lot cheaper and has SLI, which quadro doesnt have, but doesnt have a framesync. on hardwaresite for syncing two or more computers.
CPU:
1) AMD64
- best RAM to CPU coupling
For high throughput I think the AMD64 got best performance on RAM bandwidth.
- should be 3800+ since newcastle has more Cache
- Dont know if Dual Opteron would be better for PCIe? berformance...
2) Pentium-4
please help here...
3) EMT64
not Available
PCI Express:
- should have two ore more PCIe? for Graphic cards, called PEG.
- one extra for high bandwith networkcard
HD-Interface:
1) SATA (or SATA-2) with RAID-0:
I think if we got 4 Harddisks in RAID-0 Mode we could get more than 120MB/s Disk performance which is like I think the Maximum throughput of a Graphic Cards
SATA-2 has better connectors which are lockable, which is important if transported.
2) (Paralell) ATA with RAID-0
Old ATA so because of intern cabling its better to use the SATA since of the air flow.
3) SCSI:
I think its good for Servers but to expensive for workstation...
Chipsets:
1) nforce-4
since the nvidia card should work best with nvidia-chipsets and the only one now (at time of writing) available AMD64 PCI-Express Chipset.
2) ...
Motherboards:
We have to wait for above decisions.
Heatsinks:
I found at http://www.thermaltake.com/ a fanless graphiccard cooler: http://www.thermaltake.com/coolers/chipset/cl-g0003fanless/cl-g00003.htm
