A new case that appears to be gaining popularity is the Lian-Li A3 mATX. I've actually just bought one. I was looking at the D41 myself, but after seeing a few reviews and builds on YouTue thought the A3 looked a really versatile case. I've not started my build yet so it's still sitting in the box, but I had a quick play and the quality and functionality are very good. Have a look on the Lian-Li site for the various AIO choices the case will accept, it's about as good as they come at the moment, certainly at the price point.

Thank you for your reply, I had considered the Lian-li A3 mATX case, sadly it will not fit my Arctic Cooler 360 III , I watched a YouTube build, and he had to swap out the AIO, plus the lack of cable management kind of put me off.
Ideally I am looking for that little bit of extra space, I did consider the ASUS AP201, which will fit my cooler, looking at those cases led me to reading about the Jonsbo cases firstly the D31 mATX, then onto the D41, which is only 4 cms taller, but added the ability to use an ATX case, I do have a suitable Matx MB and an ATX, main difference is my ATX is a Z790, whereas my mATX is a B650m, plus I have a 140mm PSU and a 180mm PSU, I am doing my best to try and fit what I have already into the smallest cases, with the least amount of compromises, the Jonsbo D41 seems to offer pretty much everything whilst still keeping the case on the smaller size, but with the options to put in pretty much all the larger parts that I own, plus the price seems very reasonable at £64.95, I am not interested in the more expensive version with the screen.
But you never quite know what might be released soon, I've spent hours looking at cases.....it would take me less than 20 percent of that time, to actually put the system together...
