They've got lots and lots of hardware for improving normal boxes. Round cables, good heatsinks, good fans, cathode ray tubes, etc etc etc. Some of it's designed for looks, some of it's designed for performance. Some people spend hundreds of dollars building enormous water cooling solutions, to overclock their processor far beyond what it's designed to do.
Invariably, none of them are using modern hardware.
I saw one site that was someone who had built a cooling rig that took up an entire table. I'll admit it was a pretty neat system. He managed to overclock his computer to be almost as fast as mine, and only spent about four times what it would have cost him to just buy a newer CPU.
Er, wait. Almost as fast as mine if mine had one CPU.
So there's the question. Why do people spend $800 trying to make what they *have* perform better, when they could spend $200 to simply get something that performs better?
I finally realized why I felt so strange looking through these sites when I found a site with round cables listed on the front page. Round cables are neat. They provide much better airflow. I use round cables. They rock.
They had IDE cables listed on the front page. If you wanted SCSI cables, you had to search for them.
Why not list SCSI cables on the front page? I mean, SCSI's faster!
I still don't get it.
