I could say "Nice job" like everyone else but criticism also helps.
Should the case really be that close to the user? My concern would be sound..
Also cooling comes to mind, not many venting holes. Monitors radiate heat, do you want that heat to be next to your computer?
Using ACS speakers along with aiwa, do the tonal characteristics match? Also, placement of the surrounds - shouldn't they be ear level wall mounted on the left/right sides of the room.
Color coordination: white mic, grey monitor, silver case, black speakers, grey mouse, black keyboard, blue chair/mouse pad, beige desk, orange desktop.
Are your cables and components tuned and is that plain paint on the wall I see? not glazed and tuned to be acoustically sound ? lol jk
