Since running ESX 3.5 on Workstation 6 seems to be impossible, I had to find another way to explore the new features of ESX 3.5. Searching for a cheap supported configuration isn’t an easy job. You have to find a supported motherboard, network card and SATA controller. I have found a desktop with all these items combined. You can use The HP Compaq d530 - Small form factor (SFF) DG755A desktop. My model has a CPU from Intel Pentium 4 CPU 2.8 GHz, a NIC from Broadcom Corporatoin NetXtreme BCM5782 Gigabit Ethernet and a SATA 82801EB (ICH5) SATA Controller. I added a 512 Mb memory bank so I have 1 Gigabyte in total. Enough to host a few virtual machines :-).
