We've been using this to build servers:
http://www.asus.com/Motherboard/E45M1M_PRO/#specifications
While the specs are modest, it has proven adequate in a SOHO
environment. We typically build it with 4 HDDs configured in 2 raid-1
mirrors, one for host and VM software, and another for user data.

While we prefer and use Proxmox VE, I expect that it would do fine with
VB. While the 8G is a bit limiting, using OpenVZ containers let you
share a good bit of ram between VMs.

You can buy several of these for the price a 16G+ board and processor
would run you. I think this is the best bang for the buck presently.

While PVE is great for servers, I don't believe it will allow you the
flexibility of running a VM on your workstation. BL, while VB is great
for desktop virtualization, it's not as well suited to server
virtualization. I don't think any virtualization solution is well suited
to both workstation and server applications, just as workstations and
servers are inherently different.

Which brings us back to hardware. If you're doing desktop
virtualization, you'll likely need a good bit more than the E45. For
server virtualization though, it's quite nice.

We'll be meeting this coming Saturday (every 2nd Sat) at UAT if you'd
like to stop by and discuss your situation.
