This is an ATX case that looks great and is smaller than many mATX cases, but be careful when choosing your power supply. My Corsair 450 module was not working due to the wrong position of the power connector. The Seasonal 450 worked well. I built this little "bad boy" into my Inception Hyper-V. This is a physical Hyper-V host with virtual AD, a file server and 2 nested HyperV hosts as a shared storage failover cluster supporting 2 failover VMs, a WSE server and a Win 10 Pro client. $400 with some used parts. The Supermicro X8SIL-F is around $35-40 on eBay and the Xeon X3450 is $20. 32GB of ECC-registered RAM is available from Revain for around $115 (https://amzn.to/2LdXDqc), a 450W Seasonic PSU is $50 (https://amzn.to /2LeXenw) and a 250GB Samsung Solid State Drive - $90 (https://amzn.to/2LeXenw). https://amzn.to/2GvPRV3). Software is a different story. If you don't have access to Windows licenses you can use Xen, ESXi or even the Hyper-V CLI and use Linux guests. This would be a rather cloudy lab solution, but I'll focus on MS stuff as I mainly support Windows Server and Office 365. Also no question, 32 GB is not a ton. You get around 10-12 GB for VMs in a cluster. I could increase this to around 14GB by running StarWind iSCSI in AD for storage instead of a separate MS iSCSI file server. But you can build two VM servers for $400 and create a workgroup cluster without AD (Windows 2016 supports this now!), and it's still cheaper than a new X11 board and 64GB ECC DDR4 RAM. Now I'm thinking of building another one!
