Thats a very good question, luckely I thought of this and measured all of the usb ports I had lying around to make shure a standard size would fit. However there is some of those overzised plugs out there that will not fit but I have no intention to use any of those. The recesse shouldn't be a problem since a normal usb cable actually doesn't plug all the way in. There is 2mm gap on most usb connectors so in my case they will be almost flush with the material of the foot. Thank you for reading through this project and I aprecciate your comments God point here aswell and the answer is almost the same as above. I havn't measured any usb keys and there is most likely some of the bigger ones out there that will not fit. But im pretty shure a normal size one will fit. I do however see some interference with the powerplug from the PSU and the usb and audioconnectors. The PSU connector is a bit too big and also at an 90° angle so I will probably need to replace it with a straight plug. I was trying to avoid this and taking measures to be shure but it doesn't help if your taking measures from the wrong PSU. Anyway it's one of the more easy things to fix. Thanks, Im a fan of your metallworking aswell If you are nervous, then what do you think I am :S I havn't talked to the anodizer yet, but my hope is that, it won't be too vissible on the black parts and, in worst case, I only need to redo some of the other parts. But yeah, Im a bit nervous aswell.
