What to do with old File Server

I inhereted an undocumented network therefore I had to visit each PC and record specs. I came across a machine that used to be the file server. I recently pulled it out an plugged it in. The machine is running WINNT 4.0 SP3. It has a total of 4GB ofHD space, 112MG of RAM, and is a 90MHZ x86 Family processor. Drives C,D, & E are all mirrored with Drive C being formatted with FAT and D & E formatted with NTFS. I need some ideas about what I can do with this machine. I problably know the answers to my question but I am curious about what other techies think.
