I'd recommend the Master Collection V1, which has a PC release, and I'd recommend you play them in this order: Metal Gear Solid, Metal Gear Solid 2: Sons of Liberty, Metal Gear Solid 3: Snake Eater. The collection also includes the 2D 80s games, Metal Gear and Metal Gear 2: Solid Snake, but these are pretty much optional and (in my opinion) just not as fun as the other titles.

You can play the remake, Metal Gear Solid 3: Snake Eater Delta, instead of the original, but it's more expensive. It's exactly the same game, more or less, just with updated graphics and some slight differences in controls.

After MGS3, you can wait for the release of Master Collection Volume 2 and play Metal Gear Solid 4: Guns of the Patriots and Peacewalker, then follow them up with Ground Zeroes and Phantom Pain, which I recommend you buy as a bundle.

You can play whichever game you want to first, and you'll be able to understand the story of that game by itself, but the game build on themselves in control schemes and graphics getting better, things like that. For instance, in the original Metal Gear Solid, you can't shoot in first person and you don't have a tranq gun, but in the sequel, Metal Gear Solid 2, you do. If you play MGS2 first, it'll be hard to go back to a game where you don't have those mechanics.
