My current system wasn't booting, so I decided to use this as an opportunity to upgrade.
I bought this HX750 to go in a FT02 case.
However I was able to test it out and conclude that my old PSU died on my current system.
Can I use it in my old ANTEC 900 case while postponing the purchase of the new case and other components until the HD 7970 is available?
Also, since when is the bottom mount PSU not the best idea? What are you comparing this to exactly? The top mount PSU is clearly worse than an adequate bottom mount setup.
I am not a big fan of mounting the PSU with the intake fan down and only a little bit of clearance - edit - and no holes in the bottom - end edit -, but it is in no way clear that your method is the lesser of two evils, especially when we don't even know how much clearance there even is.
