They dont want you to mess everything up, you will probably touch everything and unplug a few wires.
So INGO fits in of of those small rack thingy?
And the bigger it gets, the more threads and members it has, the bigger the server needs to be?
I thought that you would need a few racks like that to host HandK's posts alone.
It's not about the number of posts, it's about the number of database queries. We have plenty of disk space, but as the traffic to the site grows, it requires more memory and more processor. Eventually, INGO will grow so large that we'll have to separate the database and the web and put each one on its own server. The racks in that picture each hold 42 physical servers. The servers are about 1.5" high, 19" wide, and (usually) around 30-40" deep.
