Does look quite nice. My concern after using my current SFF case is the compromise in CPU cooler or GPU cooler depending on how you do it (although this isn't as bad as my current case).
Reminds me of the CoolerMaster NR200P that I was considering for a while, but that case seems to require the use of an AIO (which I do sorta like).
Do we know the MSRP of the Performance 1 M?
