I found a Microsoft Sidewinder keyboard that let you modularly unhook the Num Pad and move it to the left as an option, and having a left side Num Pad has been a wonder for gaming, not just the closer distance between the home row and the mouse, but also a few games I have taken some small advantage from the closer distance for the left hand from "WASD position" to the Num Pad for commands/macros or even the naturalness in games that support it of using the "WASD hand" for Num Pad arrows. I'm now surprised left hand Num Pad isn't more common in keyboard form factors. Modular is particularly handy because there are still mouse-less data entry scenarios where it is nice to have it on right hand because left is busy with Tab and other accelerator keys.
