I hope this is allowed if not i'm sorry. I have 2 prommies that are not getting used due to to work commitments and kids. I would like to sell them to someone who could make good use of them but not sure where to put them as i've been out of the loop for a while. Also what they are worth?. One is a beige Mach 1 the other a Lian li Mach 2 gt, and various fitting kits. any suggestions please. Thanks in advance.
