Thanks for putting together such a great video about my little case project. I loved the -Self Proclaimed- comment and have to admit when I aproved the design from Paul it did not click with me, very funny though. I will look into adding some tips based on the video for the manual. For the people out there, I slide the case over the edge of desk to remove the tray screws and when you push the tray back into the corner it locates the screws. On the Blizzard 1230 mk4, mine fits but has to be connected to motherboard first then the whole lot screwed in.
Thanks again Clint.
PS I will comment on the lid, this was a dificult design decision. The reason is I wanted the lid to fold round the case so you did not see a cut edge. Add to this the rear panels fixing method meant a simple slide on lid was impossible if it was to be aesthetically pleasing. Once you know how to slide on and off it is liveable, but the cut edge would not have been.

I've got one of these (and so does Dave Haynie, as it happens) and it indeed looks fabulous. Mine is black. Mounting a brand new PC motherboard has its own set of challenges, and putting a Ryzen 9 3950X with water cooling in this small case was ultimately unsuccessful - although plenty of people, including Dave Haynie, have managed with a 3900X. Now I'm just waiting for ARM motherboards to be commonly available, and one will go into the case. It feels the right thing to do for the somewhat experimental nature of this case. Mind, the quality is better than of most branded PC cases. When I say -experimental-, it's more about the Kickstarter background, and the community around it, rather than something builr in some anonymous Asian factory.

Amiga was very popular in Europe, because it had the best graphics and sound you could get out of the box and because of crazy cracking scene that pirated every game that came out. The funny stuff about Amiga is that most of people i knew rarely had any original games. We just had boxes full of floppies of cracked games and were copying them with X-Copy from each other. My cousin was like 6 years old and knew how to copy a game which was actually pretty easy on the Amiga. I remember that sometimes you could fix a game with faulty disk by just copying it to another one. X-Copy was a very good tool.

It's a nice case, but too expensive. A case more expensive than the computer board. kinda of extreme hobbiste/geekery. It reminds me of the Nuxt board, nice and all, but the price is for rich enthusiasts.
I know (from retromancave vids) that it's a small company, etc. But I think there's a lot of people that would buy this case, if it was under 100-. I've got 6 projects that would need this case, but at that price, i'm not even gona buy one. Too bad.
Anyways, I like the dream story of this case. The guy had a dream, and went with it, made the case he wanted. it's a nice indy story!

Hi Clint. I'm sure I've already spoke about that. I bought a Sharp 32- TV set last year and it's providing a Displayport plug, except it's not a displayport but a mini-scart, and the scart cable is also provided. With a scart connector, you'll be opening your flat TV to a full world of RGB 15 Khz retro hardware. I'm pretty sure the YUV input are also able to do 15 KHz, and converting from RGB to YUV is just a matter of a handfull of discrete components, with no quality loss at all.

But wait, I'm confused about the power supply thing - isn't PAL on a different like voltage & stuff, especially like hertz (which is what makes them run at different frame rates.
The internal hardware is designed to receive electricity at the PAL rate, not the NTSB rate, right? Did you use like a step-down converter on the plug or something?
Sorry, I just don't really understand lol-

7: 17 -- -Feature due to modular design- -- i. e. No one realized that there would be an edge that would catch if you tried to slide it straight off until they were already into production. So, instead of redesigning the lid for what is admittedly an annoying but non-fatal flaw, turn the -flaw- into a -feature- (in case you can't tell, I'm in the advertising as my day job -)

Yeah I 3D printed a bracket for the SUM USB adapter and other ports not in your build form my Accelerated A600 build. I think there were standoffs on the A500 floppy drives that came in stock, but I had to shim up the A600 floppy like you did with yours. There is also a 3D printable Floppy button on Thingiverse that makes the Floppy button look a little better on the Checkmate case.

the project is a FAIL period. they shud make it for either the 500 or the 1200, the keyboard connection in the rear shud have been replaceable with either the round din or usb, the cable entry of the keyboard should have been moved to the side not the middle of the back and various cables to make it all work. U shud have been truthful and told them is it not good enuf.

Somewhere hidden in my shed is an Amiga 1200 with 68060 OC to 120MHz, 250MB HDD, RTC, 1GB RAM, USB, 2 x 3. 5- FDD, CD-RW and WiFi, all in a tower case. I wish all the aftermarket stuff had been around then: it took me a LONG time to get everything working. The easy bit was the Zorro slot CPU upgrade and the HDD, and it got steadily harder from there.
