Hey There,
I plan to build a virtual server test environment at my home.
I read through a few of the threads here and on a few other sites. Some of you mentioned that older hardware (SATA vs SCSI etc) will work with VMWARE workstation or ESX server 3.0 with the right hacks/modifications.
The last company I worked for we setup a Dell PowerEdge Monster with tons of SAS drives and specifically built it spec to order for ESX-Server operations to host a ton of virtual hosts for production server testing. I have heard some users say use VMWARE workstation for test environments and ESX-Server for production. I have more familiarity with ESX-Server and wanted to stay with that version if possible. But, I am open to input. So, I am planning to spec out/purchase a decent Dell server to host a good 5 VM's running at once at the most. The VM's will be running XP Pro/Vista and Windows Server 2003.
I just don't want to spend a lot of time guessing and researching specs/threads on finding a compatable hardware match..or for that matter talk to Dell and have them give me a hard time on providing compatable hardware info for a desktop recommendation versus pushing me to purchase a server. (It took us almost a month of back and forth with thier storage guys to provide a match for our performance/price requirements for the PowerEdge we had purchased.) If you had say around $300-$600..or maybe more.. to spend..what would you purchase for a home test box? The PowerEdge we purchased was around 5K or so....but I am really not trying to reach that kind of commitment.

I was thinking quad core with 4 gigs of ram minimum. Then I thought, quads will get me up to the 1K price range, so maybe an dual core or an AMD system to reduce cost may be the only options for me right now. I am open to any suggestions/recommendations anyone has.
Thanks for your time and input.
