I would only use the system I have built if you don’t have room for a small portable air-conditioner “Way way more efficient”. You can find a small AC unit for about $400 CAD. As with any project I would do some things different now that its all together. I would go with 10 60W units “5 on either side of a larger cold block” and liquid cool the hot sides with two more cooling blocks.
Anyway here is a quick list of similar items used in this build.
Liquid Cooling sys
12V Thermoelectric “Im using two 10Amp units”
Water Cooling Block “one of these sandwiched between the 2 chillers”
AC110V/220V to DC12V Power supply
I am assuming that you will want to upgrade the fans on that system as they are usually very week.
Hope this all helps.
