A of howtos start like that "The perfect Server" or "The Perfect Descktop" or "The perfect Setup". Howtoforge has lots of howtos like that. Their latest "the perfect server" literally shows you, ( because the howto has more screenshots then words ) how to install Centos 4.5 and the servers that you need for hosting sites with mysql, php, email ftp and a control panel - ISPConfig.
A howto for each version
This is not their first "the perfect server for centos" howto, they had one for centos 4.4 and one for centos 5.0. Wonder how much different is Centos 4.4 from 4.5 and more exactly how much different if the howto for 4.4 from the one for 4.5? Well they replaced the version everywhere in the text and luckily the install gui was similar so they did not have to change the screenshots :). For 5.0 they did not have so much luck, they had to change the screenshots, and a add some more.
Made for Robots
What I don't like about these kind of howtos is that they don't explain much about the software you're installing, and they don't tell you why you do what they tell you to do. At some point they show you a screenshot and the only text is "in the next screen click next". That's not very useful, you don't learn anything like that. If something goes wrong or if you're trying to set things up on a different distro or disfferent OS you will not know what to do unless you're lucky to find a similar howto for your distro.
One other thing I don't like is that they show you even how to install Centos. Why not do a separate howto just for that, this way I will not get bored by those installation screenshots and they would get more space for writing some more/good details about what they are doing.
