If you like playing with different things (Operating systems, misc software) - virtual machines are fun. I allocate 32 of my 128GB to 'hugepages' - basically reserved areas of memory for the VMs (or other capable software) to use. It helps performance a bit. Aside from that, I make pretty liberal usage of tmpfs (memory backed storage) for various things. When building software with many files it can make a big difference. Fedpkg/mock will chew through 40-50GB depending on what I'm building/the chroot involved
