My old long in the tooth system is in a CM690 MKI, which to be honest I still rate as a decent case in spite of its age. My only only criticism is that it's a big old beast, hence me looking for something smaller. When I started looking the Fractal North and the NZXT H5 were top of the list, but they are not significantly smaller and a tad wider. Now I've gotten a bee in my bonnet about building something more compact the D41, closely followed my the Meshify 2 Mini have gone to the top of the list for the moment. Likewise I looked at the Corsair 3000D but reviews as you say were mixed. Apparently the Thermaltake Tower 200 although sold as an ITX case can be coaxed into accepting an mATX mobo. Though I'm not sure I'd want the hassle or like the vending machine look. I had a quick look at the Jonsbo TK-1 last night but need to check the dimensions again. I've looked at so many the past few days they are starting to blur into on set of dimensions for everything...
