I recently bought an HP DL360 G5 off of Ebay to use for my VMWare studies.  It came with 8GB – enough to run at least a few instances of Server 2008 as long as each guest does not require too much RAM, but recently I have found this limiting, so I thought I’d just buy some more from Ebay – wrong! The PC2-5300F DDR2 server RAM is expensive!  This might have to wait until next month 🙁
