I have an HP Proliant ML115 (quadcore Opteron 1216 2.4GH/2.5GB RAM) gathering dust in my study. It runs Windows 2008 pretty well - I used to use it as an environment for playing with new software and technology as a general purpose storage box and svn server. Most of my stuff now runs in VMs on a MacPro and/or in the cloud so this box is just dead space at the moment. I'm not sure what to do with it:
Beef it up and use it as a home media/file server.
Beef it up, add a decent graphics card and use it as a gaming rig and/or workstation and/or media centre.
Option 3 Scrap it on the grounds that its EOL.
I would appreciate your thoughts on the relative merits and/or feasibility of doing all or any of the above.
