So I've finished refurbishing the T3500's and put them into service. #1 has 18gb of ram, 240gb ssd, 1TB 7200 rpm hdd, Gtx 750ti and an X5650. #2 has 18gb of ram, 240gb ssd, 1TB 7200 rpm hdd, Gtx 1050 and a W3680. I've also refurbished a Z400 with 12gb of ram, 240gb ssd, 7200 rpm hdd, Gtx 750ti and an X5650. That was a lot of fun putting them together and testing them. Now I'm working on a Z420, it has so far, 32gb of ram, 480gb ssd, 2TB 7200 rpm hdd, Gtx 1050ti and a E5-1650v2 in it. This has been interesting replacing all of the old broken or slow machines in our house!
