Wait what? You add all to one cart, checkout, and the parts will all be on your doorstep within a week. Ordering would take 10 minutes tops.
But if you really want to spend a couple hundred extra to have it built for you, and wait for them to orde the parts, put it together, then ship to you, I have heard cyberpower isn't bad. No clue if they sell in canada though. You will most likely be better off going to a local shop and having them do it.
Even that would take longer than ordering and building yourself tho. Up to you.
Just trying to help you out.
Yah I 100% appreciate the support, but I mean putting it together takes to long(I have no experience and it looks hard also)
