Well, I've finally retired my old G5 Mac Pro Tower, replacing it with a 1st generation Intel-based Mac Pro Tower, which my son got from one of his customers who was upgrading to the latest Mac Pro Tower.
Despite it's 'vintage' (it's about 5 years old), it's still pretty powerful. It's a dual CPU, 2 x 2.66 Ghz Dual-Core Intel Xeon processors (four-cores total), with 16 GB memory. It has an NVIDIA Quadro 4500 512 MB (liquid cooled) graphics card (the same as what I had in my old G5). It came with 3 hard drives, two 1 TB drives striped as a raid configuration for the Mac side and a 500 GB drive with Windows loaded (it's configured as a dual-boot system, defaulted to the Mac OS, but it can be run as a native Windows 7 Pro box if I wish to). It also came with a new compact Apple keyboard. The only hardware I had to transfer was a PCI card which added a couple of eSATA ports for my external 2 TB hard drive. I also had to pay for some software upgrades but all totaled, it came to just over $650. Not bad considering what I've got (new this configuration would have been something over $4,000 + software).
The most amazing thing is how quiet and cooler running this box is. The old G5 PowerPC was noisy and could heat a small room.
