Hi Erik,
Interesting choice. I'm looking for such a configuration. I want to connect this machine with one IDE drive (Virtual Center) to an external iSCSI box with open filer with 1,5 TB of data.
I want this config for ESX (for around 580 euro):
MSI K9AG Neo2-Digital
AMD X2 6000+
4 x 1GB DDR2-667
1 X DVD-ROM IDE
1 X IDE HD 40 GB
2x Intel Pro1000GT NIC
Is your configuration working properly now?
