Pluses: Solid build, nice painted finish, comes in six flat panels for easy drilling on a drill press, all steel (except for the aluminum front panel) blocks magnetic fields more efficiently. Minuses: inadequate hardware, esp self tapping sheet metal screws, but holes are perfect size for tapping to use 8-32 machine screws, rack mountable front plate of no use for home hi fi and no option offered, cutouts for IEC socket on wrong side (fuse holder is below socket hole when oriented on left rear vs right rear). Overall a very nice product, I will purchase again for future projects.
