Fractal have a good selection of cases at the moment. I've only ever built systems around ATX boards but I'm tempted to give mATX a go just to try and get something more compact.
The N3 looks to be a nice case. But I can't recall seeing and on the UK sites. That said I wasn't looking as such. It would seem lots of people are waiting on new stock from Jonsbo.
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...
While case choice and aesthetics are a very personal choice, I tend to agree. That said you like what you like. I noted the D41 screen version also has the standard mesh insert supplied should you prefer it instead. Some RGB setups look fantastic but my case is sat up a corner so other the front panel anything else would go unseen. Biggest issue with the D41 at the moment is finding one in stock. I'm sure within a few weeks they will be everywhere, however for the moment they are thin on the ground.
