I finally broke down and bought a 150GB Velociraptor for my server. I installed it this afternoon.
That server hadn't had a reinstall in 3.5 years. The Windows install survived four motherboards, three CPUs, a move to x64, a move to dual core, a move to quad core, and a switch from AMD to Intel architecture. Of course it also had several drives, etc, come and go in that time. Truly a testament to the flexibility of Windows when it comes to hardware changes.
As a Beta tester for Windows Vista, Microsoft was nice enough to give me a free copy of Vista RTM and Server 2008 RTM. However, they didn't give me a key for Server 2008 until they gave me a free technet subscription for 12-18 hours. Activation successful.
Thanks go out to the teams that made Windows such a stable platform, and to whoever screwed up and sold Technets for $0.
