Personally, I'd go gaming desktop.
-I think you can get more than you think for the money with a desktop. Skip the i7 and go for an i5. Buy a simple case on sale, don't worry about getting the most expensive motherboard if you're not going to use the features, etc. I think you can get the cost in at around or just under $1000 without really making any sacrifices that you'd notice. There are a ton of sub-reddits around building a pc and picking out parts.
Build a PC Build a PC Canada, etc. There are a ton more watching sales, etc. Beyond that, check out Redflagdeals.com and their forums. There are a lot more resources and cross comparing communities now then there used to be.
-You can never upgrade that laptop beyond RAM and an SSD. In two years you could sell your desktop GPU for a bit of a return and put that into a new one.
-If you don't want to build it, in a jam NCIX will put it together for you and test it for like $50
-Don't worry about transporting it in a year. You'll be moving far bigger things either way. (Note, I didn't realize how big a full ATX case was until I bought one thinking it wasmid tower)
-Ordering PC parts online is a breeze if you stick to reputable retailers. Just ask on the subreddits above. Personally, I just ordered all my parts from the same place on my last build. I could have likely saved a bit of money doing it differently but this was just easier for me. I can't remember if I said before, but I went NCIX last time and just drove over and picked the parts up once the order was ready.
-Amazon has gotten good for components, check prices there because sometimes you luck out.
-Check Craigslist. There's a very good chance you can get a free (Check the free stuff category) or extremely cheap desk and TV stand there.
-Likewise, I think you'll be surprised at how low cost a used monitor and TV would be if it comes down to that (TVs often go for free. I know because I always here about how people can't get rid of them if they're 5 years old and end up giving them away or just selling for dirt cheap so someone will come pick them up). If you don't like that idea, you can get off brand new TVs that will keep you happy for a couple years for like $300.
-If you can't find the right desk/table, IKEA and Staples are what you should be looking at for really cheap solutions.
