I haven't built a computer since Core 2 Duo days, so I am a bit rusty.
Approximate Purchase Date: This week
Budget Range: $500
System Usage from Most to Least Important: 2D CAD, simple solidworks, engineering programs, MS office apps.
Parts Not Required: Power supply. I have a relatively new decent brand 600wattish power supply that I will be reusing. have a PATA DVD writer, keyboard and mouse are not needed. I also have a 500GB SATA hard drive for media storage.
Preferred Website(s) for Parts: newegg or amazon (I have prime)
Parts Preferences: Intel
SLI or Crossfire: No. In fact, I will be happy with the onboard Intel GFX. Currently using a ATI HD 3400 and it does fine for what I do.
Additional Comments: I'm not looking to mine bitcoins or do any gaming in 2560X1600 with 16xAA. I am just looking to get the best bang for my buck for what I do. I have a budget of $500 and saving money doesn't earn me any kudos, so I would like to spend it all.
