No such machine exists.
Just from an I/O perspective, each 1080p60 signal is 3gb/s so we're talking 30gb/s of bandwidth not counting overhead, Also remember that signal has to traverse the I/O bus twice (once from the card to the CPU and then from the CPU to disk).
For storage you would need a 8 SSD's in a RAID 0 (assuming 515MB/s write speed) with each disk on its own SATA 6gb/s channel. I don't think I've ever seen a mother board with that many SATA channels onboard, and externally thunderbolt and fiber channel maxes out at 20 gb/s (10 gb/s shy of the 30 you would need)
The vast majority of HD capture cards max out at 4 inputs for this reason. Though I have seen an 8-channel capture card. You might be better off getting 2 machines and plugging a timecode generator into each card to keep the files in sync for later editing.
