As a long time Science Ficton reader I want to participate in answering the question "Where are they?"
My roots are in BBS sysoping. I still run a very large files download website. Now that I have the time I find myself doing the PC Technician tinkering with my PC's that I used to do with my bbs machines.
In the last couple of months I have added a Xeon with 4 cores plus hyper-threading. I have replaced a gpu that was not able to process Seti tasks. I have experimented with Windows starter 7 on two pcs. Actually getting it to install on a 1 GB motherboard. I have ordered a GT 750 Ti to replace (probably) the gpu present on the Xeon. I expect serious speed improvements from that. I have ordered a used replacement cpu with 2 cores for my oldest Seti processing box (HP dx2200). With any luck this will make it a little more completive with my OptiPlex 760 which has much higher through put than could be accounted for simply having 2 cpus to the HP dx2200's one cpu. I ran across a TeraFlop gpu for $34.99 so will see if it is even possible to use it. Happy computing!
