1u Server Case

Building a 1u rackmount server?

I've built many PCs, I spend most of my day programming etc. etc. Basically, just to let you know, I am all clued up on PCs before someone shouts something like "If you don't know how don't bother".

I'm looking at building a 1u rackmount server to put in a datacentre in London however I have never built a server.

I can't seem to find server-specific parts. I have seen server cases advertised as ATX. Does that mean you use standard ATX components like a desktop PC.

Could anyone give any advice on this matter? If I need sever-specific components could someone point me to a few places to buy these components?

Servers are just dedicated PC's so the architecture is identical.

BUT

When it comes to components and the finer detail of architecture then things change.

You need:

Server MB (this is likely to have things like added security consoles etc)
Server class memory (more expensive, but designed to be highly robust)
Server class CPU's (as memory)
RAID controller
Server Class (preferably Hot Swap) HDD arrange in a RAID (preferably 5)
Server chassis (preferably with redundant PSU's, Hot Swap HDD Caddies etc)

After that it is whether or not you want to put fun things like remote support cards etc
