Oh, I've had four (five counting an updated powersupply) Gainclones and a 47 Labs Shigaraki. Of all these, the best is one using the Chipamps.com boards with blackgates etc.(unfortunately no more blackgates in the kit, no more being made) enclosed in the Specialized kit Gainclone case. This case has a copper heat sink, does that make a differnce? Has heavy gauge aluminum, a difference? Has Maple side panels, a difference? Anyways, it is my favorite. I did not make it though.
