New Server
It says "Network File system SMB/FTP" - you really want NFS on a Linux file system such as ext3.

Does your PC do a filesystem check on restart?
How about opening a console window and run something like:-
This will at least tell you what was running (maybe) at the time of freeze.

Isn't the [42949400 etc] the number of seconds since the last reboot - about 18 months?
What does the uptime command give?
There isn't a Ubuntu 6.02LTS - there is a 8.04LTS though

Have a look at the smartmon tests explained here.
Read the capabilities (smartctl -a) to see what tests your particular drives can perform and then run them as explained in the link above. Check the results for errors (although most errors do not mean that your drive will die anytime soon).
I would second the overheating problem as a probable cause. Unless you've done so recently fit an earthing strap on your wrist, and clean very carefully the CPU fan and heat sink, but more importantly the video card fan and heat sink. You may need to detach the video card from the MoBo to gain access to it.
If the above does not solve this problem keep sshd running and when a crash occurs log in remotely and check what the logs say (both messages or syslog and xorg.0.log).
Finally a quick word about RAID. I would strongly advise against using any BIOS RAID setup because they are all proprietary software CRAP, which are often buggy and can leave you unable to access your data when you upgrade you OS later on, or worse the MoBo dies. Switch these off in the BIOS and use the Linux kernel RAID drivers which do a much better job (both in terms of performance and stability). A LiveCD is all you need to recover your data whether your basic OS goes bad or perhaps the MoBo packs up one day. Of course, if you can afford real hardware RAID with SCSI drives then by all means go for it. It will outperform most/any software RAID - but at the same time you'll need to budget for 4-7 times the money you had in mind.

I think Smarton will run.
The results look a bit chancy though:-
It only took a couple of seconds to run - and I'm sure I've transferred a lot more than 5GB!
