PC came back yesterday, front USB ports now both work as expected.
Bluetooth seems OK so far, will have to test it for a couple of days to be certain.
Had a slight issue with reactivating Win 10 as I didn't know I had to deactivate it first if you need to replace major parts, motherboard is one of them. However, a phone call to Microsoft sorted it less than 10 mins, so all good.
Also, strangely, or not, the sluggish mouse thing when the USB receiver was pluged into the back is also gone... not sure how this is resovled, same mouse, same placement of the PC... oh well...
So keeping fingers' crossed Bluetooth is resovled properly.
Thanks everyone for your help and espeically thanks for pushing me to send it back right away and the tip on insisting on the 30 days returns / refudn rights, otherwise, OCUK would just send my PC back and say no fault found, charge me a tenner for 'testing', which is still what they believe with the old MSI motherbaord...
