Fixing a laptop (by turning it into a desktop?)

Hey there! As the title says i have a "broken" laptop. It is a Hp g series (i don't have it with me right now to post the exact model) and ~2 years ago its on-board graphic card died. I was told (two different technicians agrred) the whole motherboard needed to be replaced which was around 200$ back then. I didn't repair it cause i had a desktop as well and the investment wasn't worth it.
Now i've moved to another house and unfortunately it doesn't include the aforementioned desktop so i decided to make some use out of the old laptop. Moving houses had some more effect on my laptop's state, I seem to have lost the battery charger!
I recall facing heating problems as well (which probably led to the graphic card malfunction) so i had this idea:
1) Buy a cheap tower case.
2) Remove every viable part from the old laptop :hard drive, processor, screen, keyboard*
3) Place them in the case
4) Buy whatever is missing that could make it operative again. I guess a motherboard with decent on board graphic card and some way of power supply would be enough.
In my mind i could be using the laptop's case like i used to (not moving around of course) as its screen and keyboard were the most convinient ones i've ever used. All of its "internal" parts would be connected to a case nearby which would be much easier to cool down. Replacing cost of the motherboard is still an issue but perhaps after 2 years it's not that expensive.
Am i a complete idiot for coming up with something like this? Is there a better way to deal with the 3 problems (new motherboard, heat issues, no charger) of my laptop?
I need to mention that i prefer to keep everything on a low budget.
First off, Welcome to Overclockers!

It would be more cost effective to just replace the power cord and mobo (which would likely have onboard gfx already).. though, minus windows/monitor/keyboard/mouse you could probably build a small form PC with the harddrive from the laptop for under 500.
Intel Pentium G3258 3.2GHz Dual-Core Processor (about 70)
MSI H81M-E34 Micro ATX LGA1150 Motherboard (about 50)
Mushkin ECO2 8GB (2 x 4GB) DDR3-1600 Memory (about 30)
Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive (about 45, but maybe laptop can suffice for now)
Asus Radeon R7 370 2GB Video Card (about 130, usually has a MiR for lower price)
Thermaltake Versa H22 ATX Mid Tower Case (about 35)
XFX XT 400W 80+ Bronze Certified ATX Power Supply (about 45)

all in all that's 400ish dollars and can probably pull decentish games on mid graphics settings. Of Course since you'd need a monitor and keyboard etc.. you'll be closer to 600.. not sure you're budgeted for it all in all, but its an option. I just don't see trying to turn a laptop in to a desktop being super viable if you might have to spend close to 300 to repair it.
What you're talking about doing is not cost effective and probably won't even work. The hard drive is probably the only component you can reuse. And those laptop hard drives are typically slow, 5400 rpm units. And the CPU may be soldered onto the motherboard.
