My 1st Portable Gaming Desktop Around 1000$

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Approximate Purchase Date: After feedback is recieved

Budget Range: Around 1000$

System Usage from Most to Least Important: Gaming, Solidworks and other CAD (Most noteworthy aside from that standard use)

Parts Not Required: keyboard, mouse, monitor, speakers, optical drive for now (not sure what else should go hear)

Preferred Website(s) for Parts: I have been just browsing alot of deals all my website choices are below

Country: In Canada

Parts Preferences: N/A (Already chosen parts)

Overclocking: Maybe a little, I definitely don't have the experience without running the risk of damaging the system

SLI or Crossfire: I wish but its a mini-ITX so that's not happening

Monitor Resolution: Probably but now purchased yet, 1920x1080

Additional Comments: I'm looking for any blatantly obvious bottlenecks or small investments that might pay off in longevity or performance and vice-versa cutbacks that won't reduce life or performance (any constructive criticism really since this is my 1st build).
