Any mech is capable of fielding a Guass, as long as they have a ballistic slot with enough crit space to mount it. Generally, this isn't an issue as the ballistic hard-point is in a place where there can be plenty of room, such as the Side-Torsos or Arms of a mech.
As pointed out some natural choices are (from lightest to heaviest) the Raven, the Hunchback, the Dragon, the Katapult, and the Atlas. There are others, too...
Now to break down the pros and cons of each:
The Raven
It has multiple ballistic hard-points, but they are both in the same location, and the Gauss takes 7 crit slots to mount, so you can only fit one in there. But there is room for another ballistic, like the AC2. It is, however, a lightly armored choice - and with lower tonnage you won't be able to take more more than a Gauss with you, unless you invest in some high tech (Endo-Steel, Ferro-Firbous, XL Engine, all of which are EXPENSIVE)
The Hunchback
This is actually a great platform for a Guass. The HBK variant with the AC20, already has a huge gun mounted. You can easily swap it out for a Guass, and improve your heat profile a lot! Consider, changing your remaining MLAS for MPLAS for better DPS, when you Guss isn't suitable. However, it suffers from the same problem as the Raven, all it's ballistic hard-points are in the same section, meaning there is only room for a single Gauss. (A single guass is still a heck of a thing, delivering 50% damage, around 7-8points at 1320m)
The Dragon
This Mech has its ballistic point mounted in an arm. Leaving you less likely to suffer super cricital damage if the Gauss explodes (which it will likely do if internally damaged!). Again, the one-sided hard-point only has room for a single gun. But the Arm flexing gives you much better use with it.
The Catapult
There is a Catapult variant with two machine guns mounted, one in each side torso. This is the only variant (currently) that has the right ballistic hard-point configuration to mount more than one Guass. The main weakness is, Guass are heavy - dedicating 30 tons of your 75 tons to just the ballistic weapons leaves little weight for other stuff. People often save up for an XL engine in this configuration - which has it's own set of advantages and disadvantages - the largest advantage being a lighter engine for the same rating.
The Atlas
All Atlas builds come with a huge freaking gun sticking out their right side. Some of them have many ballistic hard-points in their Right Torso, but as with all big guns, critical space limits you to a single one. The Atlas K, in particular, comes with a Guass standard. The main weakness of this mech is that it's big and heavy, and tends to be a main target when in the brawl. Also, having 100 tons of Mech hide in the bushes to snipe is really a waste of front-line punching power. But it caries the room to mount a Guass with a bunch of supporting weaponry that helps keep you relevant in many situations.
With ALL of these builds - you never want to rely on a ballistic weapon alone. It runs cooler than lasers, but relies on ammo, which you can run out of or it can get an internal hit and explode. The coolest thing about the Guass is that it can put out a decent amount of hurt at ranges that are immune to LRM fire (at 1300m, it's still doing 50% damage!) and it has no minimum range. Plus, it's a light weight when it comes to heat. However, it's fire cycle time is the same as an AC 20, with only 75% of the punch in a fist fight, for essentially the same weight.
I like my Guass built Atlas, it gives me something to fling at LRM boats when I don't feel like rushing into a tackle, but has enough punch to compliment the rest of my Alpha Strike when I do get into a wrestling match.
