heavy.. thick.. rough in appearence.. no more frills and thrills with programming.. sturdily built.. and keeps the promise up to 20%.. dissipates heat nicely.. a lots.. works like a storm.. no tiresome.. its the RED BRICK..
thin.. light.. easy to install.. no more extra frills and thrills, like the red brick.. but works nicely.. almost.. but my one extra vote goes for red brick as it proved well in my boats and ships at heavy loads.. even without water cooling.. but the SS failed.. but still works fine.. and happily both are almost same, except the heat sink.. and some devices..
