We’re a massive fan of the HP Proliant MicroServer and HP continue to offer cash back if you buy one by June 30th, they’re your ideal first server, VMware ESX lab, baby home server or test machine, not to mention an easy and great way to get into the server world. They retail at approximately £2o0 plus taxes in the UK, however you get £110 cash back meaning you can get your own HP Proliant MicroServer for £90!!!
Check out this link for more information, they’ve got a special virtualization bundle not to mention a NAS and media server bundle as well, it got me tempted in ordering another one for the lab. they are brilliant, small quiet, upgradeable and easy to use and live with.
