FPGA specs needed for bitcoin mining

[pieppiep]

I'm interested in bitcoin mining, especially in fpga mining, and I am thinking of trying to implement it myself.
I've borrowed an old xilinx spartan 3 fpga board from a friend of mine and have made a few simple small designs for it just for fun.
Now I am wondering if bitcoin mining will fitt in the board, but I don't really have an idea how big bitcoin mining will be and if it will fit in this fpga.
