I purchased one of these for a new build I'm in the middle of now. It's going to be an ESXi 4.1 box with a total of 16 drives ( maybe 18?). Six on the Intel Southbridge, 8 on the onboard LSI 2008, and 2 or 4 on the E-Bay LSI plug in card I'm awaiting delivery on. My case, a Thermaltake Armour, has 4 3-in-2 Hot Swap cages and one 4-in-3, all from Kingwin. The case also has an internal mount for 2 more drives which I may or may not use. The intention is to use 2 drives in raid-0 on the plug-in card as data store for the ESXi layer. Maybe these will go in the internal mount, allowing use of all 16 front slots for unraid. Still gelling that config in my mind. Other specs are few... a Corsair 750 watt supply, 16 Samsung 2tb 204 drives for unraid, and 2 Seagate 7200 rpm 1tb drives for the raid0 datastore, 16 gb of ecc ddr3, Xeon E3-1230 ...
I've been playing with the board quite a bit at the esxi level, learning how to migrate VM's back and forth between host and client, and such. The board runs great and I'm absolutely thrilled with the ip based KVM functionality... being able to totally power-down the server and the turn it back on from my desktop is the bees-knees...
