Hello everyone and thank you for your interest!
I apologize that I didn't update the thread or reply to any posts yesterday. Sometimes there's not enough hours in a day. I'll do my best in getting back to you all today and I hope that I'll have time to take a couple of pictures as well.
Please note that I edited the first post and the rig's CPU. I mixed them up with another set of rigs I have that aren't for sale right now. The correct CPU for these rigs is an Intel Pentium G4400, not an Intel Celeron G3900.
