hello there, I was looking today at the lian li xl tower with the water cooling kit in it, as I come to order it tonight it seems to have gone out of stock and says the ETA of new arrival is on 01/02/22, I just wondered if I was able to get the case from somewhere else and send it into you guys to build in like you would if you had them in stock, really been looking forward to getting this pc for Christmas and its just my luck that its gone out of stock, if you could let me know if this is possible please many thanks.
