- | Here is a picture of my test system, I will box this once I decide on an enclosure. I have also included a closeup of the only bit of extra hardware (other than MBHP modules) that is required! | + | Here is a picture of my test system, It is enclosed in an old Strand Tempus 2-12 case (I bought 4 very cheap!). |
