Gamdias Talos E3 is a good mid tower computer case which packs value with a "budget" price of only $59.99 USD. With support for 4x storage drives, GPUs up to 300mm in size, and 240/360mm AIOs - it has room for just about anything you would need.
I recently reviewed BeQuiet's SHADOW ROCK SLIM 2 budget CPU cooler, and found it to be a strong contender, especially when paired with a second fan. BeQuiet also sent a case for me to test the cooler with, the Silent Base 802 Window. Unlike the SHADOW ROCK SLIM 2 - this is not a budget case, with a MSRP of $169.99
DeepCool's CK560 is a nice mid-tower case that provides good cooling performance while running silently. This is a quality product that gets the job done well. I have no complaints about this product and would recommend it to anyone looking for a new computer case.
