Upgraded the Optiplex to an i7 and 16gb of ram, will be upgrading the GPU to a low profile 1050ti sometime soon. It plays games at 720p currently.
An i7-3770, some OEM Dell Mobo, 16gb of DDR3 ram at 1600mhz, an AMD 7500, and a 500gb seagate HDD are the current specs.
The Mac is used to for Reddit, as that is all it can handle.
Core 2 duo at 3.06ghz, 4 gigs of ram and a GeForce 9400. Only thing semi-nice about it is the IPS screen it has.
The rest is some Logitech gear I got on sale, a budget mechanical keyboard with brown switches, an AKG Perception 120 mic going into a Stienburg UR12, and a FiiO E10K for my headphones, the V-MODA M-100's.
The nicest thing here is my Herman Miller Aeron, which I got for cheap due to the broken back adjustment. I taped it back together, and it works great.
Any other Apple stuff is either broken in some way while remaining functional, or just very outdated.
