After looking around for awhile I think I have managed to find the items in question.
The block on the far left appears to be : http://koolance.com/cpu-300-h06-processor-water-block
"New technology has allowed Koolance to advance its patented design even further, now for heat sources of up to 300W! The CPU-300 uses a high density gold-plated copper cold plate with a cover of heavy engineering resin.
The IPC 1U rack-compatible CPU-300-H06 natively supports processors with Intel socket 478, AMD socket 462/A, and Intel socket 370. With separate adapters, it can also support AMD AM2/AM2+/AM3, AMD 939/940/754, Intel LGA-775, and Intel 603/604. The CPU-300 has threaded compression fittings for easy assembly. "
I believe that the blocks on the right are two of these: http://koolance.com/gpu-180-l06-video-card-vga-chipset-water-block
"Featuring a very efficient 200W patented design, the GPU-180-L06 has 360-degree rotational nozzles to achieve a variety of mounting directions on video card or motherboard chipsets.
Created from high density solid copper and plated in gold, the GPU-180 includes a sliding mounting bracket to fit all types of chipset mounting holes. Two sizes of bracket tabs are included, plus mounting hooks for Intel chipsets and 8 aluminum self-adhesive video memory heat sinks."
It appears what you have picked up was sold as a "complete watercooling" package as I have found multiple pictures with the all in one unit and blocks of that nature together.
Given the indication that you can adapt the CPU block to fit LGA 775, that means that this set is at least 6/7+ years old.
If you have the intention of doing watercooling, you could (if you were so inclined) use the chip only blocks on Graphics Cards. The CPU block is going to require heavy modification to get it to fit any modern socket (If that is at all possible)..
There are a few people around the Marketplace here on EVGA that are interested in older technology for nostalgic reasons. While I can't put a price on the set, I am sure that it would put a smile on some old techies face.
According to the link you found, the set seems to sell for around $100. I'm not sure if anyone would be willing to pay close to that..But you never know..
The last thing I looked at was the All in one unit. It appears to have a 5 volt pump. Modern pumps are around the 12v+ range..So while I am sure it can be used..It's far from optimal as far as watercooling is concerned.
It's worth checking out the Marketplace and seeing if anyone is into old water setups. I'm sure there are hardcore coolers wanting to take a trip down memory lane.
I hope this helps.
If you have further questions please don't hesitate to ask! :)
