To tears and heartach, lets go throught them 1 by one....
This also assumes you will be using some certain software.
- Chaintech ZNF3-250 mobo
Looking at the specs of this motherboard, i am presuming that you are using a AMD64 cpu.., but the nforce3 chipset is well suported by linux. The onboard sound (if your using it) i dont know about the support for this it may be able to use another driver. The raid controller should be fine as it is SlI Chipset these are suppored. IEEE 1394 should also be fine.
good linux choice there.
- Radeon 9600xt 256mb Video
ok, there are pros and cons about this, simply put yes it does work. cause i have one and it works fine. BUT...., it depends on the system and weather the drivers are configured correctly, you will have to use the ati fglrx divers available from here
- Mushkin Green Line DDR400 1 gig
There is usually no problems with the ram in any machine, unless you are over clocking it....
- western digital 160 gig HDD SATA
Again, you should have no problems, but be warned abou t the configuration of your SATA, Linux may not pick it up at first. but if it is initially picked up in the kernel during setup, you should be ok.
- D-Link Wireless Inernet adapter
Without knowing the exact model number i cant confirm weather it would work or not..
if you have any more queries i can help you with choice of Linux OS if you would like..
