From the sounds of it, your server won't be breaking into a sweat
trying to handle the workload. :)
If you are experiencing performance problems, you need to look at where
the bottlenecks are. Monitor first, then optimize. Right now it sounds
like you've got a lot of machine with very little load. "Optimizing" is
a waste of time if you can't see any performance changes.

delete files on the server; they can only upload or download. that's the setup
i have now. if i have 4gb of ram on my new server, what caching parameters i
should set in the samba conf file? and how do i optimize my linux filesystem to
allow optimal performance for samba?

ECC memory is useful for preventing memory errors. It doesn't
matter how long it takes to get the wrong answer. :) I recommend
it for anything critical.
The memory access speed is minuscule compared with the disk I/O
speed and network speed. The type of memory is not important. The
amount of memory usually plays a bigger role on servers.
How much caching helps depends on usage patterns. If your users are
accessing the same files frequently, it can really boost
performance. If they don't, you won't see a great performance
increase.
The processor you've chosen has a lot of power for simple file
serving. I gather from the questions, you're not doing this for a
large organization, so you're unlikely to need more performance.
You should do some performance monitoring on the server to find out
if you need to change anything. Put it up in the live environment
and see how much CPU is being used, what percentage of cache hits
you're getting, etc., and upgrade it accordingly.

thanks a lot gary. do u know if ECC memory or registered memory
helps? also how much does caching provide performance increase,
and i will be using two gigabit ethernets using link aggregation,
right now i am thinking of getting one AMD Dual-Core Opteron 275
Italy 1GHz HT Socket 940 but the motherboard allows two of that.
shall i go for two of them or just one?

if you are to build a samba file server what hardware would you
pick? does samba benifit from dual core, or dual processors or
even quad? also does it benifit from memory? and how does it
benifit from memory? more ram is better for samba? any ideas
here?

Like any file server, you'd want the fastest drives available, which
means SCSI, put into a RAID array. Beyond that, more memory allows for
more caching. Processor speed is not a huge concern unless you're
running gigabit Ethernet, in which case you may need a fast processor
just to be able to pump the data into the pipe.
