Did somebody can give me some advises on hardware
for building a Centos linux server?

What will you put on that server?

the universe were fair? Then all the awful things that happen to us in
life, would happen because we deserved them. So now I take great
pleasure in the general hostility and unfairness of things.

Look for vendors that specifically list Red Hat Enterprise Linux 5 as a
supported operating system. Most major vendors should offer servers with
this support.
If you are asking specs though, then you need to provide a lot more
details on what the server will do.
what about looking in the archives? You are really not the first person
asking this.

Depends on what you intend to to with it.
If you are going to just run a firewall - the cheapest, slowest,
smallest server you can buy will do fine. If you are going to
support the newest 'Hot Thing(tm)' on the net and handle 500,000,000
web page views a day you are going to need heftier hardware.
You did the equivalent of asking 'can someone give me some advice on
buying a truck?'
Before any possible answer can be given, the first question must be:
What do you plan to do with it?

You'r right, but I have to begin somewhere.
This hardware is intended to be a terminal server for at least 40 users
driven with LTSP.for BBx Pro-5 and Bbj applications
Need fast and huge storage, 2 lan fast connexions. No intensive mail or web
browsing, 1 or 2 outside (xtranet ) users;
back-up will be on an SLR-100 tape drive
The load for 20 users and for the last 6 years with RH9 is actually
supported by a
MOTHER BOARD : MSI KT-3 ULTRA DDR 333(3) CE (ATX form)
CPU : AMD-2100 XP
memory : 2 DDRam 333 (512MEG) for a total of 1024meg
1 scsi controller adaptec 29160 SCSI
3 hard disc SEAGATE CHETAH ULTRA SCSI-ULTRA-320 LVD (68 pin)
It have been enough for that tme but users number is raising and by the way
an upgrade of the computing capacity will be usefull.
I checked recently for an ASUS S775 P5Q-VM G45 PCIE MOTHERBOARD with an
INTEL CORE 2 QUAD Q9550 2.83G/1333/12M/S775 with SATA hard disc no Raid
I doesn't seem to be a server board and I'm not shure of that choice.

Maybe you just want to pick real server hardware? Pick one of Dell RXX series.

thats desktop hardware. no ECC support. anything running a business
application for 50 users is probably mission important or mission
critical, and undetected creeping bit errors due to lack of ECC would
be, in my book, unacceptable.
I'd probably use a HP or Dell 1U or 2U server, with redundant power, ECC
memory, and at least mirrored system drives.

Where can one find info or studies on this sort of thing? I use non-ecc ram
in several servers, and of course most ppl use it in their desktops.
Wouldn't bit errors result in crashes or data corruption? Or what would the
results be?

It's very unpredictable. Since linux tends to use all available ram for disk
buffers, the first thing is likely to be corruption in disk files. By the time
you see crashes or anything visible, you may have a lot of invalid data.
