I have 2 PCs.
One is a gutted/modded old Alienware case from about 10 years ago. Used to be my gaming PC but is now basically a HTPC:
i5 2500k
16 GB Ram
240 GB SSD, 500GB & 2TB HDD
I THINK 700 Watt PSU
Gigabyte GTX 960 (which replaced a GTX 460 which replaced a GeForce 7800)
Panasonic 50" HDTV
Logitech Wireless Keyboard & Mouse
The other is a pre-built (Don't judge, I was in a weird emotional state and the price was REALLY good) that I use as my new gaming rig
i7 6700
16 GB RAM
240GB SSD, 1TB HDD
600W PSU
ASUS GTX 1070
Dell 27" 144 Hz G-Sync monitor
Logitech G602 Gaming Mouse
