None, I still haven't found a case that truly has everything that I want from a case, which is:
-Decent position (IE: exhausts air) for 120.3 radiator (and maybe a position for a 120.2 as well, or 2 120.2s), pump and so on.
-Built in reservoir in a good/striking place (maybe make the side window a reservoir?).
-Not humongous (with some decent thinking this is possible), or stupidly heavy.
-No 'overkill' drive bays - who needs 5 5.25" bays, and over 5 HDD bays? For those that do, there are many cases available, but for those who will use the bare minimum (like me, 2 SSDs, 1 HDD and an external ODD), it feels like unnecessary weight and space.
-A decent in-built fan controller, which can be controlled through Windows, where you can set temps for the fans to come on/go off and so on. The only things near so far are the Heatmaster, BigNG and Aqueros, all of which are German (so support is a pain, manuals are badly written for English, and no-one has any experience of them), and the Heatmaster and BigNG have terrible software.
-Classic looks. FT02 for-instance. Lian Li V-series. And so on.
-An external finish that doesn't scratch/mark if you look at it (Lian Li!) - Silverstone's is an improvement, but at first it doesn't look as good.
-Covers for those bits that don't look brilliant (PSU and ensuing cable mess, drive bays)
-PSU connectors mounted into the motherboard tray, and are connected to a modular-like panel by the PSU - much easier cable routing - IE, none required. The panel would cover most of the required connectors (maybe 2 8 pin PCI-E, 2 6 pin, 4+4 pin CPU, 24 pin ATX and so on) then conventional connectors could be used if anything extra is required. Short cables would be used to connect the plug on the mobo tray to the relevant connector.
Maybe not all of that, but they are almost all things that just aren't included in any case.
