It's an i7 4770 not a 4790. Didn't come with pci wifi card either, just usb dongle thrown in. few dings here and there and the latch on the card door has little crack but works fine. Swapped harddrives out with old pc's and it hasn't had any issues other than Cubase and Spectral layers crying about the CPU fingerprint. Threw in a few more sticks of ram, bringing it up to 24, (can have max of 32g) added an AMD Radeon HD 5450 from old SSF and an NVIDIA GeForce GT 730, they don't fight each other so that's a plus. Also unlocked cores & processors, and dropped in intel wifi 6 AX200 160MHZ.. It's fast enough for Audio and Video editing, I don't play demanding computer games,  so I have no idea about gaming performance.
