Varnish, Nginx, Apache, APC, Meteor, Cpanel & Wordpress On A Single Server, Any Good?

Yes, I have read many close questions, but I needed a specific answer and hence this question.

First, these are my new server specifications: Linux Server (CentOS), Intel Xeon 3470 Quad Core (2.93GHz x 4) processor, 4 GB DDR3 Memory, 1TB Hard Disk Space, 10 TB Bandwidth and 9 Dedicated IPs.

AIM: To speed up my wordpress blog + Increase server's capacity to handle heavy load

PLAN: This is how I am planning to setup my server - - VARNISH (in the front, to cache server responses) >> NGINX (to effectively handle static content & overcome the C10k problem) >> APACHE (behind Nginx, to effectively deliver dynamic content) >> APC (PHP page, database & object caching) >> CPANEL (which requires Apache, and I require it) >> WORDPRESS >> W3 TOTAL CACHE (caching plugin for Wordpress).

So , will the setup work? Have anyone tried it? Please shower your thoughts and knowledge.

NOTE: I can't do without Apache because I am used to that .htaccess & Cpanel stuff. So, it's not any option. All others are options. Please try to help.

I hope I am clear in what I wanted to ask.
