Record to pc

Hi all I was just having a thought and wondered if its possible. I have a couple of sat boxes that I use at home with hard disks installed in each of them. I was wondering if instead of using the hard disk could I direct my recording to a PC? That way I could watch any recordings on any box in any room
Cheers

Amazing why didn't I think of this before. Got everything pointing to 1 hard disk, cheers so much for ur help
