I needed the unit cause my other one was damaged by lightning. For the price, these are not bad. I cracked it open because I planned to replace the HDD with a 1TB and add an M2 drive as well as more memory. The inside looked pretty clean, but the included 256GB drive was trash. Looks like the outer case of the drive has some damage as well. Oh well. Haven't loaded my Linux OS yet but will do soon and edit review if anything changes. Overall I'm pleased so far.
