Rep Rack for small depth

Hello,

I'm looking to install a Rack or Half Rack in my garage, with a depth limited to about 47 inches and a height at 80 inches.

I'm wondering which is the best option to fit these dimensions:

• a 16-inch PR-5000, with two more 16-inch cross members to mount it on the wall, not sure if that's possible?
• a 16“ PR-5000 with front feet, but slightly over 47” deep
• an apollo half Rack with a depth of 48 inches

I'm thinking that the first option might be the most scalable and practical if it's feasible.

Thank you!
