I too shall be watching, be careful, but do keep us posted!

Definitely will be watching the progress on this. The question remains if the method will be worthwhile for the added cost - I suppose if you had a huge farm this would be meaningful. Perhaps in 6-9 months, you can buy everyone's used Klondikes, overclock it to hell and prolong it's useful life since your electricity costs will be lower when factoring in the electricity for cooling in large scale.

I've seen this done with pcs and just a heads up If at any point one of those asics dies and the board needs reworked to replace one you might as well toss the board and start over. That oil gets under the chips and will burn when heated with hotair from a rework. Once you do get it off if you get the board "cleaned" off the solder sometime won't stick properly and thats not really something you want to chance on a QFN package. Again I've built computers for a long time and had buddys do this. It seems cool at first but in the end the effort is not worth the end result. What you end up with is a large tank filled with hot oil that you have to work around and inevitably gets all over everything. Not to mention you still have to cool the oil somehow. I think the ideal solution would be to sandwich a waterblock between two klondikes or bitburners. That would make it cost effective because you have one heatsinking device per two boards and you can use off the shelf pc water pumps controllers and radiators.

Small scale designs is what I personally want as long as it is modular.

Depending on the number of boards at what point does it really make sense to do this?
Depending on overclocking at what point does it really make sense to do this?
Is it suitable for home applications?
Waste heat can it heat your water tank?

Those to me very important questions as well as yours BenTuras before going ahead. Personally I do not want to stop with one tank 10U - 42U capacity. Have to start small obviously with a 5U to 10U capacity as I suspect that the minimum for such a project to has look at the economies of scale. At some point it makes sense to use a system like this. If you are talking aquarium etc I think that is a great starting point for a proof of concept but will it save money? Waste heat might be useful though for heating your pool or house water in general.

Going to source tanks first that has same sort of dimensions as a rack server on its back.

You're in good company: http://www.datacenterknowledge.com/archives/2012/09/04/intel-explores-mineral-oil-cooling/

I have also been thinking about this, I have chips for both Bitburner and Klondike boards coming and also have a large fish tank to use for this.

My main concerns are:

Is it worth it, given the expectation that the boards will probably be costing more to run than generating BTC within a year.
It can become messy, handling oil dripping electronics
It will be a mayor disaster when the tank bursts, so I'll probably put the tank in the barn in the back of the garden

Cooling computer servers using air is inefficient and costly. As a result, some companies are returning to an older technology to cool data centers: submerging the hardware in liquid. Results show that significant energy savings can be achieved using their system in a super-computing environment.

Why not do the same with Mining Farms?

As some of us poor souls are blessed with year round ambient temps of 28C plus and possibly reasonable costs for electricity but also keen on larger farm configurations I was hoping to pool our ideas here into thread about mineral oil submersion cooling. Personally I will be working on a DIY system for this in Indonesia. I will try and document the progress here.

Basing it off the Green Revolution Tank system.
