Can I put a AMD FX 4-Core Black Edition FX-4300, FD4300WMHKBOX in my stock cybertron trooper x-68

No because your cybertron PC comes with a dual core AMD A4-6300 Richland Dual-Core 3.7 GHz (is Socket FM2) And the one that you are wanting to put in is the AMD FX-4300 Vishera Quad-Core 3.8 GHz (is Socket AM3+).
That means that your motherboard supports socket FM2 and the FX-4300 is socket AM3+ so it won't work.
