Bootup speed I boot up in under 5 seconds from power button on to login screen. I'm running Linux natively, and I login to a i3wm session so that portion takes less than half of a second once I type my password. Not that I ever reboot, this thing is on mining 24/7.
Mining performance I'm mining Ethereum on this at ~55mh/s. I haven't OC'd anything, or flashed VBIOS, everything is stock. I could probably get another 10% or so by flashing and OC.
Storage SSD is a must for your primary drive.
The 2 x 2TB Western Digital drives are setup in RAID 1 and I use those for secure backups (cryptocurrencies and client database backups).
General review Everything is great, especially the case and the old IBM Model M keyboard. I love this case though, I can't stop staring at my computer.
I can't max out my RAM no matter what I do (running a game with two VM's open and everything is responsive/snappy).
