Actually, you used to get pretty solid performance for the price/form factor from Apple. For instance when I purchase my Mac Pro desktop in 2008. It was a RIDICULOUSLY good deal for what you got. The Xeon processors alone were $1500 each on NewEgg the day I purchased it. They've just progressively gone less and less value, as the years have gone by.
Not doubting the price you were seeing in NewEgg, but find it hard to believe you couldn't build your own PC with the same CPU and equivalent RAM, GPU, cheaper by sourcing the parts from retail stores yourself. Was it a case where Apple was getting an incredibly good deal on those?
$3000 got you 2 x 2.8ghz Quad core Xeons, up to 64GB of FB-DIMM ECC, 4 x drive bays + 2 x CD bays.
There isn't much this thing still can't handle, it's just being phased out, and eventually it won't turn on one day.
