The conversion looks lovely, but I would not have used MDF, in fact I would not consider that stuff for anything much. The smallest sign of moisture and it swells up ruining all your work. It is also hard to screw into it long end (split) and in the USA they somehow seem to be convinced the dust is highly toxic and you need a whole bunch of protection when you cut it.

The main advantage is probably cost, which if you need to do a lot of work with relatively little amount of material is not going to be a big benefit.
