Antec DP503 Mid-Tower PC Case Review

Complete System

Building a system inside this case was such a breeze. Everything is really nicely laid out and well-spaced, so component compatibility is just very high overall. As I said before, there’s a big focus on cable management in this case, partly through careful placement of routing holes and straps, but also just with lots of space under the shroud and behind the motherboard. It means you can just slap the right side panel on and cover up any sins easily enough.

The CPU cooler has loads of room too, with support for up to a 170mm cooler, you’re not going to be limited on options.

There’s excellent clearance in the top too, so larger radiators and fan configurations won’t be an issue.

I’d have liked a rear exhaust fan, but it hardly feels necessary as there’s so much airflow in from the front fans, and lots of passive exhaust in the top and rear sections of the case.

Speaking of the front fans, they do look superb. Sure, you can remove them for 140mm or add your own, but honestly, I don’t see the need, as these are really nice quality. They’re providing a full-case-height wall of cool air, and the ARGB effects look superb too.

The PSU shroud is neat and tidy, and of course, provides those additional fan mounts should you need them.

GPU support is great, with up to 375mm of space, meaning even the biggest cards such as the 357.6mm long STRIX RTX 4090 will fit easily enough.

With all the panels back in place, the interior lighting from the front fans is more than enough to show off the internal hardware.

Plus, the fact the fans are set quite far back means they light up the case, and not so much your room, which I certainly prefer.

With a few taps of the front panel button, you can quickly and easily cycle through various colours and effects. However, there’s a header to sync with your motherboard if you so desire.
