Of this beauty a Silverdraft Demon coming in at a hefty $49,500! You need this for proper MAME gaming! ;)

Actually, if you closely look at the Q&A section, they don't recommend it for gaming. Plus, only 198Gb memory at this price and no SD card slot ? C'mon.

We would not suggest this super high end gaming workstation for gaming. As the processor and multiple video cards of this type are not geared toward gaming.

Riverstorm

@mitu - Well shoot! No gaming and you would think you could get a SD card slot (or dare I say, two!) for that price. I knew it was to good to be true at 50 grand.

198Gb...it's impressive, that's almost as much RAM as our boot drives on M.2 SSD's.

Kind of off topic but that's the other thing Intel is doing that I don't care for are the newer KF chips. Basically they have the unlocked multiplier (K--as always) but the (F) means no integrated graphics. There's nothing like having a way to selling defunct chips.

They failed QC for one reason or another with the integrated graphics but they still sell them at almost the same premium price as the regular K chips that have integrated graphics.

Companies like Dell are picking them up (I'm sure at a discount) and re-purposing them in their Alienware line.

Anyway a minor rant for an otherwise great gaming rig!

You could get approx. 1,400 2GB Pi 4 with collectively 2,800 GB of RAM for that, or 660 8GB Pi 4 with 5,280 GB total RAM, and then build a RPi cluster:

(Yes, there are newer videos of RPi clusters, but this is the most beautiful that I know of. 🤩 )

That said, actually I would very much like to see how such a cluster would fare against the Silverdraft Demon. 👹

Whew, that's going to take up it's fair share of space for the Pi's alone. Minus racks, cooling, power, etc. for the Pi's I used the bigger number just for fun.

Pi dimensions - 56.5 x 85.6 x 11 mm = 53.2004 cm^3

53.2004 cm^3 x 1400 = 74,480.56 cm^3

So if those calculations are correct you're going to need 74,481 cubic centimeters which is roughly 745 cubic meters for the Pi's alone. You're gonna need a fair sized room!

OR

The Silverdraft Demon - 43.18 x 43.18 x 27.94 cm

Riverstorm

Don't forget you might need a bit of extra room, a mm or two for the SD card protruding from the side!

mitu

@Riverstorm I think you can netboot the Pi4 without the sdcard, since now the bootloader is in the EEPROM, so you don't need any storage for the systems.

Riverstorm

@mitu - I like the way you're thinking, with a bit of creative engineering we've already reduced the footprint! I think we're on to something here... ;p

That's true, but a) it's cool, and b) with a little work on the interior design, you may be able to actually live in it! 🤓

(The video's creator already had shrunk the power supply quite good by serialising it.)

I wanted to say that to both of you guys. One thing that remains is a proper name. Off the top of my head, the rather unspectacular "MegaPi" came up, quickly followed by "ClusterF*ck". 😉
