Yes. A good starting point would be a Xilinx SP605 kit.
It's about the $750 for a decent 5370 and includes
many points from Bobs option list.

use as a PCIE card in a pc or mac
onchip CPU that can run Linux with DDR ram etc
Fiber optic link
can do massive DSP
FPGA design software and embedded software included
