You're joking, right? I've been beating them off with a stick, and this is the Antipodes.
Recently, instead of an Opteron setup, I went for an A64 on an Asus SLI nForce4. It's smirking at me while I type this. It may well be the twin 10000rpm drives, but by God it's fast - in both Windows and Linux.
I skipped the Opteron setup because it used a Tyan Tiger. Unlike the Thunder solutions, it relied on a PCI Gigabit-E controller and RAID was just software anyway.
Due to a stuffup from Gigabyte with their product variants, the Asus was cheaper. To my relief, it presents way better than cheaper stuff from Asus (eg, made in Taiwan rather than the other place). For anyone in the market however, models from both brands are pretty much identical - same chips, same functionality, similar layout.
These boards fix just about all my nForce 3 reservations: true high speed GbE and four native SATA ports, as well as the benefits of socket 939 such as four DIMM slots and vast memory bandwidth. No longer any need to feel intimidated by Intel chipset solutions.
I just had a fight with myself over getting another one - to replace yet another motherboard with infected capacitors - but financial reality reared its ugly head and I settled for a socket 754 nForce 3.
The only downside I can think of is the cursed 8000rpm chipset fan. It may be quiet, but we all know the little bastard will fail eventually.
