I think the tank is working as it should, I'll move on to the having the power transistors turn the Peltier power on and off.  It has been quite a while since I worked on this and I'll have to look at the schematic to remember the details. The printed circuit should be mounted next to the meter.  I'll have to order cooper water blocks, pump, and a cooper radiator.
The heat is going to be taken out and replaced with the radiator which I keep forgetting. I was just looking at a way to easily mount the fan to the heat sink and remembered it will be removed.
  On the tank probably the best way to get water in and out is put screw in fittings, glue on a top with a fitting there also.

  I have my order in at Amazon, pump, water blocks, and radiator probably a few other Items I'll need.  I began straightening out my notes in another notebook, schematics to be copied and all.  Not really happy with the on off switch I put in, and actually not sure how much difference it makes since the water averages out the temp.  I'll have to try it out then make decisions from the results.  I'm wondering how long a tank at 32 F takes to warm up.

  I'm still working on bringing my notes up to date. Things should begin being delivered in 4 days.

Notes are up to date, I should put in a parts layout of the circuit board  and I have to connect the circuit board to the slide in insert.

The pump should arrive today,  guess I'll pick up some tubing and see what happens when using water that is circulating which will slow the cooling process down.  I'm set up to use two Peltiers if I want.  I'll have 2 loops the cooling starting at the tank to the CPU and back to the tank. The second loop cools the hot side of the Peltier and goes to the radiator.  Looks like I have to buy another pump.

  I did a little shopping at the hardware store, fittings for the pump, hoses.
I was hoping to find something to get in and out of the tank, the fittings I
bought for the pump have pipe threads and a nut will not work.  I decided to glue on the top and run tubing through a hole, I do have some threaded brass rod I can use that I can use nuts with. 
  Rather hot day and I just got home and I don't feel like doing much, nice day for a hot pizza and then ice cream.

  A few things to get done, the tank needs a top and the top needs tubes to go through the plastic, I'd like a threaded rod with nuts for a good mechanical connection.  I'll stop at a different hardware store today.  The second attempt at putting in the bottom seemed to work well and it's a bit of extra work but I'll use the same method on the top.

I was able to find the threaded rods and a package of assorted nuts, the nuts will work with plastic pieces that I have but since the threaded rod is smaller I prefer to work with that.  I'll have to buy brass tubing that fits snuggly in the threaded rod and in the hose.  The top piece consists of 2 pieces of plastic separated by about 1/8 of an inch that is filled with silicone, the two pieces will be lowered in and rest on plastic pieces glued to the sides.  A bit more difficult than the bottom since I could go in from the top to spread the silicone.  I'm not sure how I'd get it apart for repair so it has to work the first time.
  The circuit board is attached to the slide in piece, I'll put in some led indicator lights and a rheostat to control the temp.  I think the radiator is to come in today but that is used for the Peltier hot side, much better than the large heat sink I'm now using.

Carl, are you using the same coolant on both the "hot" and "cold" sides of the peltier unit? If so, I STRONGLY advise against it. If you're going to liquid cool the peltier, you're going to need a second cooling system, because using the same system on both sides of the peltier is like trying to cool your house by leaving the freezer door open. I would personally just use the large heat sink on the peltier's hot side and be done with it. Far simpler, more efficient, and more than adequate for your needs... unless, of course, you're trying to get your CPU to absolute zero. Tongue Cheesy

It is designed with 2 loops, Hot side to radiator and back, Cold side to CPU and back.  I just ordered another pump for the hot side.
I'm working on the top for the tank that contains the inlet and outlet.  I began wondering if just using a water block would do the same thing with much less work.  I began wondering how much pressure the pump makes and the ability of the pump to withstand the pressure.

  A pump and radiator may be here today, I'm still working on the top of the tank, a slight ledge has been put on the 4 sides which the pop rests on, a layer of silicon and a second top piece.  I still need to drill holes so the water can get in and out.  I'll need Y adaptors if I need two use a second Peltier for cooling, I should test the tank and two water blocks for cooling effectiveness.  Lots of unknowns to deal with.

  I got the pump and radiator, work on putting the top on is at a stand still.  To get the in out holes lined up I taped the top and bottom together, the bottom piece had one hole drilled through it, I used that hole to drill the top piece, and drilled another set of holes on the opposite side, putting it together I realized one piece was upside down not allowing it to go in the tank.  Unable to use that for a top now,  I'll have to go buy another piece of plastic.

  I found a small piece of the plastic at a reasonable price so I have a new top, much easier to fit it in than the first one, just have to get the holes drilled in it.  I was unable to find a Y connection to run parallel water blocks.

  The top came along great, holes in the right spot so both pieces slide in and out nicely,  both pieces held together with threaded rods with a spacer in between for a silicon seal.  Still a piece of cooper that has to be cut to allow the water tube to pass.   I have just the tool to cut the cooper but it's finding it.  Trying to go slow take everything in consideration before going to the next step.  Putting both pieces together without air bubbles might be tricky.

So much dedication is impressive Carl  Smiley

Would love to see some photos if you get a chance.
