Thanks for the plug (I'm the ClockBlock designer) but this isn't accurate. The Clock-Block requires an input clock signal in the HF range and won't work with a PPS signal. However, a TAPR Reflock II (http://www.tapr.org/kits_reflock_ii.html) could sort of do this -- it can steer an oscillator to GPS via PPS signals, and that oscillator need not be at something simple like 10 MHz; it could operate directly at the motherboard's clock frequency. So you would still need to provide a piece of decent-quality quartz in the solution.
