PS - Sorry for the book, but thanks a ton for your replies and suggestions!
Do you have any more information on your Corsair Water Cooler? Perhaps we can recycle that, as well as your dual GTX 950's, your HDD and hopefully your case if it can support an ATX-sized motherboard.
The Corsair Water Cooler is definitely dead. One of the ports on the water block is no longer providing enough power to run a 240mm fan and the system will start, but very shortly afterwards, shutdown due to thermal overheating.
>> should I go for another water cooler, or use something like a Noctura NH-D-15, or even the Dark Rock Pro 4 that
puw2 posted above?
For me, Quiet is more important than absolute lowest temp.
The hard drives can definitely be reused, however I'm very much looking forward to using the new M.2 or NVMe drives.
Regarding the case, yes, it will definitely handle and ATX motherboard and have plenty of room for all the goodies. My only concern is with the USB 3 ports on the front panel, I think they've seen too much wear and tear as devices plugged into one of the ports would need to be seated just right to be recognized. I also like the cable management of the new cases better, but for now I may need to stick with what I have.
Note: I would buy a new front panel, but the case doesn't seem to have any markings to indicate a manufacturer, just a generic barcode. I think it's an old Lian Li Case, but I'm not sure.
I still have the Cooler Master Silent Pro Gold 1200W power supply as well, BUT I have no way of knowing if that has been damaged by the frequent and sudden power drops; it might read ok to power on, but will it perform under a load... I'm reluctant to use it.
Also, I have 5 fans to use; two of which are Noctura NF-P12 redux 1700 PWM fans. The others are a mix of Corsair radiator fans and standard Cooler Master fans.
>> For the CPU, is the $320 difference in price between the 3900 and 3950 worth it for an additional 4 cores? I dunno, but I suppose it's like having an additional quad core cpu added to the system, so I'll have to give that some thought.
note that the PSU is currently at 15$ on Corsair's website. I don't know if this is a mistake or an actual sale, but I would recommend grabbing that ASAP before the promo ends or the mistake was fixed.
That would have been a sweet deal, unfortunately, it appears I've already missed it - likely a quickly spotted error on the website.
For a workstation build with such a budget i'd suggest you to look into this build i listed in a
PCPartPicker list
b450 tomahawk max will do just fine with 3900X as long as your not planning on overclocking it.
if you are planning on that i'd suggest something like a
X470-F , but as you can see that tanks up the price of the build.
I probably won't do any overclocking, as it seems the temps cpu temps rise pretty dramatically if that is done, so stock would be fine, however the option of using cards in SLI is of great interest - even if I cant afford to do that with properly powerful cards right now.
>> regarding the 950's in SLI - can I still use those in either of the system you guys posted without bottlenecking the performance?
... on a slightly seperate note, is there a good way to test the old sticks of ram without a working system to plug them into? I would like to sell some of the old parts if I can.
Again, many thanks for the replies and advice!
