The 'ultimate' thread would start out with caveats. Like usage of Windows OS is a definite exclusion.
I mean describing the hardware purchases involved for something like a triple server strategy with a Samba server running two RAID6: one with SSDs, and another with 2TB drives on a 2nd gen Areca SAS HBA + 4GB cache upgrade + BBU platform. A Percona/MariaDB MySQL server with a 4-socket motherboard all populated with quad-cores and all DIMM slots populated. Then a nice single socket with a Intel Q9950/X3360 cooled with a vapor-phase cascade (-60 celcius at full load) overclocked to 4.5GHz for the TFS installation. All directly connected two each other with teamed pairs of Gigabit links. Now that might scratch the surface of creating the Ultimate OT tutorial.
So really, ultimate is an inappropriate adjective for your real target goal.
If you really want to do something useful, perhaps a tutorial on compiling MySQL 5.5 from source and using the binaries to replace the ones included with XAMPP/UniServ. I'd Rep++ for that.
