zedekk :
some of the motherboards i see like dell poweredge r410 can use socket 1366 cpu like xeon w3565, but from what i can tell require ecc memory. I have tons of standard memory and would help a lot if there is a lga 1366 socket motherboard that i can use the memory i already have on, also would need to put large graphics card in so needs x16 pcie, and preferably another pcie expansion slot in addition to one for gfx card
zedekk,
I have a T3500 purchased for $53 +$24 in Dec '15 and upgraded.
1. You can use non-ecc DDR3-1333 RAM in a Dell Precision T3500, It's triple channel, 6X slots, up to 24GB so 6X 4GB or 3X 8GB would be the thing to use.
2. The T3500 has: Two PCIe x8 slot wired as x4 (half-length); two PCIe x16 Gen 2 graphics slots; two PCI slots
They are rated to use 2X x16 PCIe 2.0 GPU's up to 150W each.
3. If you do buy a T3500, have a look around for a deal on a PERC H310 RAID controller. Get the low profile one and not the server one with the very tall heatsink. For about $60 you can change the 3GB/s disk system to 6GB/s . I did this with a T5500 and the Passmark disk score changed from 1940 to 2649.
I have a T3500 and T5500 and both are 100% reliable, very good performing considering that I think of $53 as close to free as possible for a workstation, and these systems are very quiet. The power supplies are more or less server quality. I don't think you can find a less expensive way to use the CPU and memory you have.
Cheers,
