If it has dedicated servers then so what if the matchmaking goes down. We played HL1 for shit'n'giggles at the last lan just to see the stoopid frame rates. Plenty of HL1 mods still get played and have active servers. Most new integrated GFX laptops will play HL1 brilliantly - great when you are stuck in a hotel due to snow with only a "normal" works laptop to hand (a time when steam really shines).
Its not the cough that carries you off but the coffin they carry you off in.
