unless you want the warranty, I will say no based on similar fleebay offerings.

  That's the quad core version.  Here is a similar one but can't confirm if the same video card as original posting:


Back to the original question, can't comment on value as I've not purchased a Desktop system in a few years (and built the last one).  Unless you are needing one now, keep checking Newegg and Woot for something cheaper that meets your needs.

I personally think this is a good deal relative to most other deals spoken of on FW where folks are looking to get a high-end machine by procuring a machine that has "the bones" to go high-end but needs some modifications/additions to get there and here's why:

I run a Z420 in my home lab currently E5-2660v2 and 128GB of RAM (8x16GB DDR3-8500R). The beauty of this box is that I got the E5-2660v2 for $115 on eBay and the 128GB of ECC RDIMMS for $180 on CL and the box outperforms an I7-7700k, has more RAM than I believe the i7 can handle, and if you add that up with this price ($370, $115, $180) I get $665 for a screaming fast box with 10 CPU cores, a wicked passmark score and more memory than I can stick in anything Core I3,5,7 for a fraction of the price.

The Z420 is (to the best of my knowledge) high-quality parts.  I believe it has 600W, 90% efficient PSU.  The case is sold, well organized and has a fair amount of room for expansion.   The motherboard has 5 PCIe slots (incl. dual PCIe x16 slots) and 1x PCI 33MHz slot), 8x DIMM slots, room for 3x 3.5 HDDs and has 3x 5.25" bays.  Best of all for me, it runs cool, *very* quiet and in my configuration, I was drawing < 200W with a 95W CPU, 1x WD Black drive, 1x SSD and a Nvidia 7300GS (if you can't tell already, I'm a virtualization junky).  

Full specs:

Here are some threads where people discuss expanding Z420s for your reference:

CPU options thread:

Memory Options Thread:
NOTE: This chassis was only ever *supported* with 8GB DIMMS (maxing at 64GB), but I've read others get to 128GB w/ 16G RDIMMS ('R' meaning ECC Registered vs UDIMM where 'U' usually refers to non-ECC Unbuffered) and then I did it myself with dirt-cheap PC3-8500R 16G 4Rx4 DIMMs):

You're not going to find a lot of reference points for the Z420s with Ivy Bridge (v2) E5-26xx but the main point of fact to be aware of is that of the Boot ROM (which will be a bit of a crap shoot unless you can get the seller to confirm it for you).  But the info on the boot ROM is in the CPU thread and summarized here:  

  1. To determine if the Z420 can support the v2 CPUs, look in the F10 BIOS setup for the boot block date
    - If the Z420 has a boot block date of 12/28/2011, it supports only the v1 CPUs
    - If the Z420 has a boot block block of 03/06/2013, it supports both the v1 and v2 CPUs.

The one other option I have found since my Z420 is that of a Thinkstation C30.  It's about the only way you're going to get dual v2 Xeons in a relatively small desktop form-factor case.  They seem to be few and far between to find, but if you can get your hands on one of those chassis, you can rock dual E5-26xx v2 CPUs which will allow you up to 24 CPU cores in a single chassis (48 vCPUs/threads!) 

Now all of this said:  If you are a gamer, you don't probably care if it's a Sandy-bridge (v1) or Ivy-bridge (v2) Xeon and v1 Xeons can be had even cheaper (I originally got in on an E5-2670 on eBay for $50 about 1 year ago) and again, this will beat out most i7's on the market at a fraction of the price.  And if you're a gamer, keep in mind that you face diminishing returns of single core performance X number of cores.  So if you run a single E5-2670 for example, Passmark says you have a score of about 12k but if you double up and run dual E5-2670 CPUs, you only get about a 50% increase in performance (about 18k) and for a gamer, I believe, your GPUs are doing a lot of the heavy lifting, so you're probably better off spending the extra $$ on a better GPU than putting into a dual-CPU socket system and the additional CPU.

Good luck to anyone that jumps on one of these and feel free to PM me if you have questions!

OMG is this CPU for real?
CPU Benchmark says this is 11,000 Rated!!!

Add the GTX 1050 someone was selling for $400 and this is a gamer high class machine for less than $800
