Thanks for the link, Drew. I love the thought of having a SATA PX-716.
However, they don't offer the rebate on the serial drive. Here's how the prices break down.
PX-716A at BestBuy: $149.99 + 7% (tax) = $160.49 - $30 MIR = $130.49
PX-716A at Newegg.com: $139.99 - $30 MIR + $3 (S+H) = $112.99
PX-716SA/SW at Newegg.com: $142.99 + $3 (shipping & handling) = $145.99
= At the cheapest, your paying a $33 premium for the SATA PX-716SA/SW
Not sure if having a serial drive is worth that much more, even though I like it!
