Thats a tough call Oregonian. But if you are a 100% sure that you won't be selling the rack I'd say go for it. Also, there aren't many full spec racks out there (not that I've seen) and it may be a case that the parts are worth more than the sum of the whole. As I can imagine a lot folks collecting these component by component. So even if you did end up selling the rest, you might not lose out monies wise. But that's hard to call.
From a collectors point of view of course - it may seem absolute sacrilege! But IMHO life is too short and you could own something else that will no doubt give you a lot more pleasure. Like a 1280 for e.g.
The seed has been planted in your mind now... You'll start to begrudge it sitting in the rack before long haha
