An Intel Core i7 2600 is about 10X the speed of a Xeon 3.2 and is $310
12 GB Corsair DDR3 is $140
An OCZ Vertex 2 120 GB SSD is $220

Definitely not multiple thousands of dollars but still 10X the CPU
performance, 3X the RAM, and a much faster disk.

Want more reliability and double the disk read throughput?  Add a
redundant disk with software RAID1.  That will easily outperform the 6
disk SCSI3 array.

Want 10X the networking performance?  Add a 10 GBaseT NIC for about $500.

Agreed about no ECC and no redundant power but honestly those have never
been big issues for me.  After all, LTSP is all about serving desktops
so desktop reliability doesn't seem so out of line.
