I had a look at the SFX100. Whilst I am sure it is a great system, it made my head hurt just looking at the required shopping list . I don’t have the patience to build a system from the ground up, and would rather pay the extra, and have a pallet of pre-built goodness arrive on the doorstepJust timed the reloads, and they were between 6-10 seconds, so nothing to worry about.
Mine is on a SSD so a little quicker than some i guess.
You would be better with the SFX100, far stronger and cheaper,
