With the new MX5 series we have enlarged the size of the display and added more keypad functionality. This double drive bay PC insert incorporates a vacuum florescent 20 character x 4 line USB display and a 15 button keypad. The MX5 also allows you to plug 4 fans and 6 temperature probes directly into the back of the unit for all you quiet and cooling PC needs. Includes everything you will need to get going.
