Looks like I'm going to have to buy a motherboard/CPU/memory.
Case: salvaged from a SysteMax BAX4200, (4) 5 1/4" external bays (2) 3 1/2" external bays and a 3 1/2" internal bay, fits ATX motherboard. Floppy drive one of the 3 1/2" external bays
Power Supply: Thermaltake TR2-430w
Seagate Barracuda 3200.12 - 320Gb - 3 1/2"
Seagate Barracuda 7200.11 - 500Gb - 3 1/2"
Western Digital WD5000BPVT - 500Gb - 2 1/2"
Seagate Momentus Thin - 320Gb - 2 1/2"
Fujitsu - 320Gb - 2 1/2"
I'm sure if I dig around I'll find even more.
Optical Drive: Toshiba Samsung DVD Writer Moder TS-H653
Video Card - Dual VGA version of the NVIDIA GeForce 6600 GT, Came from the same SysteMax system as the case
CPU Cooler - Silenx Ixtrema IXC-120HA2(hoping it will fit, designed for AMD Socket 754/9xx/AM2 and Intel 775)
Operating System - Some flavor of Linux with KDE
Motherboard: Gigabyte GA-78LMT-USB3(Rev. 6.0)
CPU - AMD Athlon x4 860k Kaveri Quad-core 3.7Ghz Black Edition
Ram - G.Skill Ripjaws series 8Gb kit(2x4Gb) - 240pin DDR3
(2) Bytecc Bracket 25525 - To mount 2 1/2" & 3 1/2" drives in 5 1/4" bay. (holds (2) 2 1/2" or (1) 3 1/2" drive)
Purpose for the system will normal use(lots of internet video) and data storage. I've got a number of older systems and I'm sick of having to remember which system has what I'm looking for on it. The CPU is probable extreme overkill for the use but I don't want to have to worry about it not being fast enough down the road. Usage may change.
