I recently bought a B250M-DS3H Motherboard for my HP Pavilion A6130 to put a new system on it , as the old Athlon and Nvidia 8400GS were technologically ancient. I brought the system and the new parts to a local Hardware Shop and they told me that they need the Front Panel Cables to be marked to be able and connect them with the motherboard. I felt a little bit uncomfortable as I thought a PC Builder that has built many PCs on the past , should know the Front Panel Cabling. So I need the Front Panel Cabling . They are all gray . There is a FirmWare cable I don't need and I instantly made out what it is because it was pink. But there are 3 more . A big yellow connection , a big white connection and a smaller white connection which I think is the USB 2.0 port , correct me if I'm wrong please.
By the way the old system had :
HP Pavilion A6130 Case
Asus NARRA2 Motherboard
Athlon X2 64 4400+
Nvidia GeForce 8400GS
Old Seagate Hard Drive 320GB SataII
HP 300W PSU
and the new will have :
The same case
RX 570 Pulse ITX(So it fits in here)
M.2 SSD 128GB
500GB Seagate Drive 7200RPM
320GB Old Seagate Drive SataII
2x120mm Fan (1x Front of the case , 1x side panel)
The 2 120mm Fans will be mounted by me with zip-ties.
Also the motherboard was already out of the case so we can't just copy the cabling to the new one.
Sorry if I wrote too much.
Edit: There are also 1 slim white connection and one big black connection.
