Well my little HP M40L finally died and didn't think it was worth getting a new mother board at $165. It was running WHS2011 but it just felt slow and bloated, so I installed Windows 8.1 on a spare 240gb SSD, setup DrivePool and was back in business and what a difference, maybe I fried the MB with the new speed.
So I picked up an ipen boxed HP ML10 v2 with 4gb ram and the i3 processor. After reading aroung there a re a few tricks to install windows 8, apparently it's not a supported OS, yea I know I bought a "server" so I should be running a server OS. But I like the simplicity of DrivePool and I don't really want to start messing with raids with mixed capacity drives.
SO is the ML10 v2 with the i3 overkill? I was tempted to grab a desktop AMD board and processor, because of the price, pull the 8gbs form my 40L and get a Lian Li PC-Q25B case and rebuild. BUt I don't think it would have been as cheap as the HP ML10.
