Once Again More Questions:

01. You mentioned cooling the Hard drives in the first post, Will that loop be separate from the high pressure/low temp loop?

02. Have you decided on the parts yet (Motherboard, CPU, GPU, RAM, HDDs, PSU)?

03. Which sides are the front and back of the case?

04. Are you going to mount the PSU directly to the aluminum side or are you going to make a cradle/carrier for it to be supported by?

05. Is the bottom compartment bowing/warping downward due to the weight of the compressors or is it an optical illusion?

06. If it is not an illusion do you trust in the strength of the current case or will you reinforce the bottom with crossbars or some other method?

07. What type of pressure and temperature measuring devices are those and where can I find more details about them?

08. What diameter copper pipe is that?

09. Are you using flared fittings on the copper pipe?

10. If 09 is yes, what is your method of leak testing for flared fittings with odorless gases?

I use a spray bottle of VERY soapy water and look for bubbles around the fittings when I work with propane. It works most of the time but I wonder if your technique is any more reliable.
