Had the Tower for 2 days when CAREFULLY  replacing  "Tempered" glass side panel, it shattered in my hands. Was NOT bumped on anything just placed on the lower cradle for securing it literally exploded. The tempered glass kept it from breaking into small shards but were still small in scale (1/2" to 1" in size).Great computer in terms of CPU power though. Tough to fit additional SSD's since the cables but up against the mother board and exposed pins (be careful to notice exposed pins since then can easily break).
