Brian lists it as $309 but I have seen it lower ($279). When you consider the three components it is 'replacing', that is only $60 more than I thought I was going to spend.
Then I revisited the Coolermaster HAF Stacker 915R. These units are designed to sit on HAF Stacker 935. They can either provide extra storage, room for liquid cooler or a separate computer.
I ended up getting a 915R as it can provide significant storage options. It is 22.75 inches long which is on the very long side but just manages to fit onto the NAS shelf on my server rack (it is 23" square).

Options ...
- EVGA SuperNOVA 750W G2 220-G2-0750-XR - length 7.1" / 180mm
- Corsair AX760i - length 6.3" / 160mm
- Seasonic SS-660XP2 - length 6.3" / 160mm
- Antec EDGE (550, 650 or 750) - length 6.7" / 170mm
- Thermaltake PS-TPG-0650DPCGUS-G - length 7.1" / 180mm
- Silverstone ST55F-G - length 5.5" / 140mm
Once the case arrives, I'll mock up a cardboard version of the various PSUs and see what each will look like. I already have a paper version of the motherboard that I am planning to use so I can see the cardboard PSU v the paper motherboard options. I wonder if I connect these two items if I can get it to POST.
If I am going to get custom cables, I need to check which PSUs are supported. Oh dear ... too many considerations and options.
I found these ... AeroCool Deadly Silent 120mm fans ...
