@JDW As always, I'm terrible at trying to find alternative capacitors. Any you would recommend for the 100uF caps since they are on backorder?
Thank you for alerting me to the backorder status on Mouser! I will update the text description.
If you would like the exact same part number I used (bearing in mind there is nothing too magical about it),
Digikey has stock here.
Alternatively,
Mouser has these alternatives in stock which will work just as well, since they are all SMD solid polymer (NOT "hybrid") with very low ESR. Some are 5mm in diameter which is what I used in my video, but 6.3mm diameter SMD caps will fit just fine too on the LC575 Mystic motherboard.
By the way, there is a big benefit to using OS-CON (or similar Aluminum Organic Polymer Capacitors) over Tantalum (solid or polymer) which I will explain in a forthcoming video on overclocking. Suffice it to say, you are definitely on the right track using the same or similar caps I show in my video above. Please let me know how your recap goes!
