If you want to step up to medium format, it would seem to be economical for you to do this. However, MAC Group has MAC-on-Campus http://www.mac-on-campus.com
did you try to spec out a similar system there? Its not clear if this is what you did but it may be worth a look since, although I have only personally used it when I purchased a Seckonic L-758DR and saved some money so this may be an option.....
You also have to consider Hasselblad's reasons for putting this item on such a seemingly substantial discount...I am not offering any commentary simply suggesting that this may be considered.
I owned a H3Dii-39ms (sorry if this review is not up to the standards of my more "modern" reviews, but it was written a while ago when I had this camera) http://brianhirschfeldphotography.com/2011/12/07/hasselblad-h3dii-39ms-and-80mm-f2-8-lens-2/
and image quality wise it was very pleasing and certainly a big bump from the cameras I was using at the time (Nikon D700, and Nikon D3s). I did take some very pleasing images with this camera, and many others with the H system (H2+P65+ and H4D-50) later on.
My last comment would be, I assume this is buying the camera directly from Hasselblad? I would suggest looking at dealers in your area (or globally) since buying from a dealer (assuming they are offering the same deal) a) builds a relationship b) generally gives you some sort of technical support c) may give you a better price then rack rate, although on something this heavily discounted I'm not sure this is relevant....support is really big, I know when I was learning how to use my 645DF+IQ180 I had a number of questions which DT's support team responded to quickly and efficiently and helped me learn the system and overcome the difficulties I was having.
Also you seem to be only considering new cameras. There is nothing wrong with a used camera, my H3Dii-39ms was used, and you may be able to get a better camera (mp or performance wise) or different system for the same cash outlay (money spent) by shopping around the used market. Again, I would heavily suggest going to a dealer since then you can get pictures of the camera you are getting, information on its condition, a trusted source, and technical support (as well as some sort of guarantee that it remains working I would assume). I would caution against ebay for the obvious risk reasons....
As I said I purchased my H3Dii-39ms I purchased it used (for a price not much different then the price point your looking at, and considering this was a few years ago, so consider depreciation on higher-mp systems which is a lot) and I purchased it from Adorama, because they had a used one for a price that pleased me at the time. While Adorama is of course trust-worthy and offers certain guarantees, it is not the same as ordering from a dealer because when I had questions, Adorama has no support structure in place (at-least not one that I was aware of) and I was left going around to the different forums asking questions which, while helpful, was not the most efficient way of going about it and I would have valued someone I could email at all hours of day and night.
Also consider the price of new/used Hasselblad H lenses...it is much much much higher then Used Mamiya lenses which are in some cases just as good...something else to consider when looking at building a kit AND buying into a system.
Those are my thoughts considering I was in a similar situation to you a couple years ago.
