It's a shame that it doesn't look like Toshiba's going to be selling these power miser PCIe boards anytime soon. Seems like they'd be perfect for HTPCs.

"The PCI Express x1 card houses a 65 nm Cell BE processor running at 1.5 GHz (compared to the 3.2 GHz in the Playstation 3) as well as four active SPE units (PS3: 8) and 128 MB XDR DRAM memory (PS3: 256 MB)."
