As far as the rear eSATA port goes you might be able to...
* Acquire an eSATA to SATA adapter
* Remove one of your case slot covers (or any available large enough hole going through the case).
* Run the eSATA (with SATA adapter) through the hole directly to one of the motherboard SATA ports.
The reason I mention this is because I experience a very big improvement in boot times after disabling theASM1061 Storage Controller & uninstalling the ASMedia driver in Windows. The time it now takes to get to the Starting Windows screen is simple amazing; I would say it is maybe three times faster then before. The ASMedia driver is a real hog.
