hey this is what i have been making!
please tell me if i need to fix anything
i am currently working on the metall piece
Materials are great. All I’d say is the edges on the black box are so sharp. May want to bevel those just a tad.
Bevel the casing, make the metal plate less reflective and maybe blur the reflections a bit.
The circuits look a bit flat, I’m guessing they’re just a texture. If you’re using a bump map, kick it up a bit, and if not, add one.
Also the DVI ports are too boxy; usually the metal wraps around to the front a bit, and they aren’t quite rectangular.
Otherwise, looking good! 
oh thanks^^
i will try to fix it
