So I've seen people cool their PC's with mineral-oil, water-chilled CPU coolers, and put their PC's in fridges. How come I have yet to see anyone build an air-tight(ish) PC case cooled with a window AC unit? A 1500W PC system should produce about 5,000 BTU of heat, which can be accommodated by a $150 window AC which can run continuously without trouble (assuming you don't mind the enormous heat generation or power bill . https://www.amazon.com/Frigidaire-F...coding=UTF8&psc=1&refRID=JN3CTT79E0ZKYFBRPSR4 You are dehumidifying the air at the same time, so you shouldn't (maybe?) have any condensation issues. You should be able to build a relatively air tight PC case with MDF and some hand tools to house the whole thing https://diyperks.com/product/custom_pc_case_kit/ For $200 and a bit of time, you could do this! Please do it for me. My wife won't let me. I wanna see pictures.
