Advice needed on workstation build: ASUS Z9PE-D8

Hey guys, I'm currently putting together a new workstation build for work. My budget is around ~3500 and I'm looking for something with a large # of CPU cores and ram that will be fairly extensible in the future. I opted to go with the Z9PE and the lowest end Xeon chipset that's compatible. I also considered the EVGA SR-X, but I prefer the smaller form factor. (although it's not a deal breaker). The case I'm looking at right now is the coolermaster cosmos II, but options are limited because the motherboard is eeb.

My thought process is that I'll go with the E5-2620 for now and then upgrade to the 22nm line of Xeon's in 6-8 months if I need more power. Similarly, I left a lot of room and excess wattage in case I need to upgrade to more RAM or an SLI GPU config.

My sticking point right now is the cooling/case situation. I could really use suggestions for dual processor cooling/case setups that work with an EEB motherboard. I was considering the Corsair HL100 and the Intel BXRTS2011LC, but I don't know that the cosmos case has enough clearance. Does anyone have any experience building a rig that's similar? I could really use suggestions for a case/cooling system, but I'm also totally open to any advice on the build in general. I'd be especially eager to hear from anyone who's built a similar rig for signal analysis or audio applications.

Thanks so much for any help guys, I appreciate it.

Also, sorry I couldn't use parts picker, most of the parts I'm using aren't options.

  1. Hey pbbrunet,

    Just saw your post. It's pretty old with no replies, so I was wondering if you ever got your questions answered. I went thru a lot of the same thot process before building mine.

    I settled on the HAF X case with Dynatron R17 CPU coolers. They are small but adequate for Xeons.
    The case supports extended ATX form factor boards which have same mobo dimensions (13" x 12") and the standoff pattern is mostly the same. I found 2 missing standoff holes. Unfortunately they are located in critical areas where support is really needed (in the middle-top and middle-side spans where there isn't much other standoff support. So I was going to drill and tap my own; but than decided to just ground off the threads on the brass standoffs - the threads that would normally screw into the case. And then I simply attached them to the motherboard. So they still touch the case for decent support and they still prevent the otherwise inevitable board warping when pushing in RAM modules.

    You mentioned possibly expanding RAM later. You probably already understand this by now... do not underestimate why they package DDR3 RAM in kits. I originally opted for two 32GB kits because I wanted 64GB; but couldn't find a single 64GB kit. I thought it would be fine, but learned otherwise. BIOS will lower the frequency to 1333 and if one wants to run at the 1600 advertized, one needs to force it in BIOS. But when I did that, it became more unstable. I was told that mixing large kits on this complicated board (2 CPUs w/ integrated controllers plus memory controller on mobo next to each RAM slot) is not advisable if you are expecting to run the RAM at rated frequency, timing, and voltage. Because the two kits were not tested as one, there easily may be compatibility problems between individual sticks. This incompatibility may require you to drop the frequency and raise the voltage to loosen things up for for better compatibility.

    Cheers
