All told there is definitely $3000+ worth of equipment / furniture there, but much of it I bought over the past several years or at a significant discount. I was able to get several of the higher priced components on sale (Black Friday deals ftw) or from online friends for very cheap. I bought the motherboard, CPU, RAM, and SDD from a former Battlefield teammate for less than half what they all cost retail, and he also sold me the center 27" monitor for less than half. Below is a breakdown of what's in the main rig and what each piece would typically cost retail.
Case: Cooler Master Elite 431+ ($55)
CPU: i7-3770K ($350)
CPU Cooler: Corsair H55 Hydro ($60)

~$2813 total
The desk I bought on sale at Office Max, the craptop is a free hand-me-down from my dad (dude, it's a Dell) and the 120Hz monitor for my second rig was a Christmas gift. Most of the second rig is built from leftover components I kept after upgrading as well. I've definitely spent a significant amount on this setup myself, but I've also been working on it since I moved into this house ~6 years ago.
Now if you want to see what a
real baller setup looks like, check out Hiko's streaming setup in the pictures below. The monitors and monitor stand alone are probably worth more than my entire setup.
