If you give me a list of more precisely what you're looking for, I can give you a quote. I've been doing this for about 4 years now and you can either pay me directly, half up front, half on delivery and I'll get the case, mod it and send it to you or, you can pick up a case, send it to me and pay the full price of the mods up front and I'll mail it back to you. Turnaround time depends on how extensive the mods are and if I'm going to be doing any painting. Standard stuff like removing fan grills, installing fans and lights, sleeving PSU's, turnaround time is just over a week from when I get the case, painting adds another week. Changing LED colors on a rheobus is a flat rate depending on the rheobus.
