The home built "cluster" is not something new. A lot of academics have been doing this for years, sometimes in their labs, sometimes at home. The small cluster is pretty much dead (as per Chris Dadginian). If I wanted to do a lot of number crunching, the way to go would be to get a dedicated 8-core machine and likely use some kind of accelerator (GPU or other). If I wanted more juice, it does get tricky. A serious number crunching cluster needs some fast interconnects, etc, which are not cheap. The fact that he is not familiar with now much parallel code is written in Fortran is a little troubling. I wonder how much he knows about Infiniband, high performance storage, cooling, etc, the tricks that lead to real high teraflops --> sub-petaflop performance, cause if I am not getting that, then his offering has limited use.
