SSD/HDD upgrade kit for Sr4mini,can install 3 of the 2.5inche disks of 7mm 9.5mm thickness,it has its own power supply for the disks,so the ssd/hdd dont need power cables,just need sata signal cable.which will greatly simplified the cabling,also the ssd/hdd expandsion board acts as a power filtering(lots of panasonic oscon solid caps)/distribution (Synced load switch)to power pcie plug,mb tray(cpu/directplug).so,you barely cant see a single power cable with this PSU,will release it and accpet orders soon.if you guys want order this special psu set for Sr4mini,you can tell me you need GPS(Guniq Power System) for SR4mini (with multifuction board and MB tray),
