As long as you run LE from a SD card you shouldn't have to worry about screwing any hardware up. In fact K's S905 LE builds are built to run from SD at this point unless you want to install to Nand which I think may be possible but is not recommended. Most of us use OE or LE (yes and of course there's many others) because of the 23.967 fps problem, you get a major judder every 40secs which happens when you run Kodi on an Android based system. The OE and LE project have resolved this (codesnakes work I believe) as well as many other improvements, sound sync issues being a major one as well as improved playback and file compatibility.
As far as I'm aware the S905/x boxes are not that simple to set up with LE as you need to mess around copying device tress etc which may be easier than it sounds but as I don't have a S905 I couldn't say. The S805 running LE plays back H265 fine although it can't do 10bit files and never will.
So if you want to play then a cheap box may be the way to go but check who's had success by reading through the main S905 threads. Some members here have even created specific builds for certain boxes but as said these 'specific' boxes may still vary spec wise. Worth noting the amount of RAM and Flash memory as there are often two versions of the same box.
If money isn't a problem then just buy a Wetek Hub, I would if I had the money!
