See below.

Probably more like $700.00 total, apparently. $100.00+ does matter, ~15%

Sure. Finite Element grid/mesh generation & subsequent analysis, often 
coupled w/ CFD grid generation/analysis. Fluid-structure interaction 
problems (deforming SRM propellant grains under stress from the flow 
resulting from their combustion). Reasonably well resolved 2-D (i.e., 
not 3-D, thus I *can* afford pretty good 2-D resolution, borderline 
large-eddy type resolution on the fluid side, similar resolution on the 
solid side since I spend most of my CPU time on the fluid side & don't 
want/need to answer needling questions about skimping on resolution 
*anywhere* in the analysis). Turbulent, sub-sonic/transonic, complex 
internal geometries on the fluid side, largish deformations on the solid 
side. Definitely CPU/RAM intensive, not quite so I/O intensive. Local 
drives large enough to catch the results, then processed by another box 
on the LAN (where the Tecplot license lives), but still by me, i.e. only 
one user at any 1 time. These boxen are like droids, w/ only 1 master, 
not dozens like most public servers. I/O is less important, 
CPU/RAM/stability are paramount.
