Told about that pile of junk what I got from my uncle. Well, the GPUs were R7 240 OEM (in fact an okay spare card in case of emergency), HD 3450 (it has that DMS-59 connector dammit) and there was hella lot of different RAM:
-SDRAM SODIMM 128-256MB sticks
-SDRAM 128-512MB sticks
-DDR SODIMM 256MB-1GB sticks
-DDR 256MB-1GB sticks
-DDR2 SODIMM 256MB-1GB sticks
-DDR2 256MB-2GB sticks
-DDR2 FB-DIMM 512MB-4GB sticks
-DDR3 SODIMM 1-2GB sticks
-DDR3 1-2GB sticks
So unfortunately no 4GB DDR3s, though 18GB is more than enough for that rig. At least I have more than enough RAM for any retro project for the rest of my life (I had also hella lot RAM already)
I could also use that powered USB hub as a charger if it gives at least 10W.. need to google that. A D-Link one so not some nonbranded Chinese crap.
edit: "The DUB-H7 features seven Fast Charge USB ports that are designed to provide an increased maximum charging current of 2.4 A to connected devices when the DUB-H7 is in Fast Charge Mode.", that's great as my best chargers are 2A ones
